A message, signed by Kate, attached to the wreath read: "In memory of the Australian and New Zealand soldiers who made the ultimate sacrifice for our freedom."

As part of UK events on Saturday, she also joined a service of commemoration and thanksgiving at Westminster Abbey.

Earlier, a dawn service took place in London, attended by the Princess Royal.

Princess Anne laid a wreath at Wellington Arch, Hyde Park Corner, at 5am, at the event which included a reading of the John McCrae poem In Flanders Fields.

In Australia, several services were disrupted by booing from small groups during so-called Welcome to Country ceremonies, during which indigenous leaders welcome visitors to their traditional lands.

The outbursts in Melbourne, Perth, and Sydney - where one man was arrested - were also met with applause and cheering from large groups of those gathered to pay their respects, according to local media.

The Royal Family's official account on X paid tribute with a picture of troops from the Australian and New Zealand Army Corps (ANZAC).

The image shows soldiers travelling to the First World War conflict zone Gallipoli, with the caption "Lest we forget".

Anzac Day is held every year on 25 April and was initially established to commemorate ANZAC troops landing on the beaches of Gallipoli in northwest Turkey in 1915. The attack on the Turkish defences began at dawn.

Ceremonies, which are marked across the world, also took place in Gallipoli and Villers-Bretonneux, a French village which Australian units helped defend during WWI.

Booing at ceremonies

Australia's defence minister Richard Marles criticised the disruption at ceremonies, which in previous years has been perpetrated by anti-indigenous rights protesters.

"To boo in that way goes completely against that. It is deeply disgraceful," he told ABC News Breakfast.

In Sydney, police confirmed a 24-year-old man was arrested for "an alleged act of nuisance", and several others were moved on.

They represented "a small handful of people" compared to about 11,000 at the event, according to a statement from police.

The official readout was that this was a long-standing away day with advisors and the inner cabinet to discuss the content and framing of the King's Speech, in which Labour sets out its agenda for the next session of parliament.

But the big question now is whether Starmer even makes it that far.

Ask his team and they will tell you that the PM intends to fulfil this mandate and serve out his full term as prime minister. He is focusing on dealing with the effects of the Ukraine and Iran conflicts and planning around that.

But that is not what most people in his party and around his cabinet table are talking about. They are talking about how Starmer might be replaced and who might be the one to do it.

When I ask around those in, or plugged into, the top circle, there is a view settling that Starmer will not be the prime minister to fight the next election.

A few weeks back, the prime minister looked in a better position than he had since his near political death experience in February, when more revelations about Peter Mandelson prompted a crisis which led Labour Scottish leader Anas Sarwar to demand the PM resign over "too many mistakes made."

His party thought he'd handled the UK's response to the Iran war well, while his more muscular approach to Donald Trump was being well received both in his party and a public overwhelmingly ill-disposed to the US president.

But the latest debacle around the Mandelson vetting scandal has put paid to the progress the PM had made in calming nerves in recent weeks, with the events of recent days draining Starmer's already depleted bank of authority to the point where even some in the cabinet have displayed a sense of weariness or reluctance to defend their leader on the morning rounds.

The fallout from the leak to The Guardian that Mandelson had failed his vetting, which saw the sacking of Olly Robbins and days of coverage of who said what and when, only cemented the view amongst his detractors that the PM lacks judgement and is not up to the job.

One former government adviser was bemused by the dismissal of Robbins because it created an entire new news cycle that the government very much didn't need, pointing out if Starmer had suspended him and called for an investigation, he could have better contained the fallout.

As it is, the Foreign Affairs Select Committee is now hearing from Robbins' predecessor Philip Barton, who was opposed to Mandelson's appointment, and the PM's former chief of staff, Morgan McSweeney next week.

One senior party figure tells me they think there's "agreement he's not around for the next election, but the when and how and who? Ask 10 people and you get 10 different views."

Another minister says they believe Starmer's team knows he will not fight the next election, and it's a question of when, not if, the PM has to go. "He has to go."

In my conversations with people in the party in recent days, what emerges is that there is no settled view on what might happen or who might be a likely replacement. That the cabinet is not aligned - and that many in the cabinet are quietly considering their own bids - makes it more difficult.

There is endless talk about Angela Rayner, who is well-liked in the party, but has the question of her tax affairs still unresolved. All eyes will be on what sort of intervention she chooses to make after the local elections in May.

Wes Streeting is apparently going to the pubs for drinks with MPs, but as one of his supporters points out to me, the health secretary would need a coronation because he couldn't win with party members. That means getting huge momentum in the party, which is not moving as a pack at all.

There is also enthusiasm from many about getting Andy Burnham back and crowning him. But that route is complicated, and those who might want it would need to back Starmer now, to give Burnham the time to get back into parliament.

There is talk about Yvette Cooper, Ed Miliband, or possible caretaker PMs in Lucy Powell or John Healy, the defence secretary. It is, as you can see, messy, unclear and lacking organisation.

Layer on to this atmosphere a set of very difficult local election results, and the next few weeks look very uncertain indeed for Starmer. If the results come in as bad as are feared, with Labour being hit hard in the Northern red wall, Scotland, Wales and London, then it could prove to be a tinderbox moment.

"People are nervous before acting before the local elections, and the No 10 spin has been [that] we will have to have a general election and that will lead to a Reform government if we oust Keir," says one Labour minister. "But I think after the local elections, all gloves are off."

Another senior party figure tells me that it could get very messy after May: "I don't know if there is a move against Keir because under party rules it's still very hard to pull off. It's more likely that a trickle becomes a flood, and then he needs to go as he comes under pressure, and some key people don't back him up."

In February, when Scottish leader Anas Sarwar went over the top and called for the PM to resign, he looked behind him to find no one had joined him. The question now is, will Starmer still command the confidence of this cabinet after these elections in May?

But what is also true is that many in the parliamentary party do not want a leadership challenge. As one told me this week: "Keir is far from perfect, but I don't think the country needs the drama and chaos of a leadership battle right now."

That MP also made the point that there is "no clear replacement to coalesce around".

The uncertainty and internal divisions in the party are what Starmer's allies hope will help keep the prime minister in post for now, but they can be certain of nothing come polling day.

Klaudia Zakrzewska, 32, from Essex, was involved in a collision in Argyll Street, Soho, in the early hours of Sunday morning.

She was taken to hospital but died earlier today.

Former X Factor contestant Gabrielle Carrington, 29, of Broadfield Road, Manchester, was charged with attempted murder, grievous bodily harm with intent, actual bodily harm, dangerous driving and drink driving.

She appeared at Westminster Magistrates' Court on Tuesday, 21 April and was remanded in custody to next appear at the Old Bailey on Tuesday, 19 May.

Following Ms Zakrzewska's death, the charge of attempted murder will be amended to murder.

Detective Chief Inspector Alison Foxwell, who is leading the investigation, said: "We would like to express our deepest sympathies to Klaudia's family and friends in light of this tragic update. Our thoughts are also with everyone impacted by this incident.

"We recognise that this case has generated significant interest and discussion on social media, however, we would urge the public to refrain from further speculation.

"We also ask that people do not share graphic footage out of respect for Klaudia's loved ones and for those who have been injured. The circulation of such material could also undermine our ongoing criminal investigation and potentially prejudice future court proceedings."

Two other people were also hit by Carrington's Mercedes outside of the Inca nightclub, a 58-year-old security guard who suffered life-changing injuries and a third woman, who was treated for minor injuries.

Ms Zakrzewska, a TikTok and Instagram influencer known by the name of Klaudiaglam, had over 270,000 followers on Instagram.

A GoFundMe page set up by Ms Zakrzewska's mother has raised over £18,000.

Carrington appeared on TV talent show The X Factor in 2013 as part of a girl group, making it to the third week of live shows. Now a social media influencer, she has more than 360,000 followers on Instagram, under her account RielleUK.

During her court appearance, Carrington made a heart sign with her hands towards friends and family in the packed public gallery as she was led out of the dock and back to the cells.

West Midlands Police said the woman, in her 30s, remains in custody on suspicion of causing or allowing the death of the children as investigations continue into the blaze in Wolverhampton at around 8.30pm on Friday.

Two boys, aged one and three, were pronounced dead at the scene.

Detective Chief Inspector Kylie Westlake, from the public protection unit, said: "This is a truly tragic incident, and our thoughts remain very much with those who loved the children who have been lost.

"We understand the shock and distress this awful incident will have caused to many people and we are working at pace to ascertain exactly what has happened.

"Officers have arrested a woman on suspicion of causing or allowing the death of two children.

"While we would ask people not to speculate about [the arrest] or the wider incident, we would ask that anyone who can help with our enquiries, and who is yet to speak with us, to get in contact."

Two other children, and a woman, were already out of the house, on Mason Street, before emergency services arrived, police said. They were checked over by medics, but did not need hospital treatment.

Police have cordoned off the end-of-terrace house, which was extensively damaged, while work is done to establish the cause of the fire.

On Saturday morning, forensic officers could be seen entering the property wearing protective equipment.

The walls of the house appeared scorched, while two ground-floor windows were open and blackened with smoke.

Russia fired 619 ​drones and 47 missiles, Ukraine's air force said ⁠in a statement on Telegram, adding that it shot down 580 drones and 30 missiles.

Five people died in attacks on the city of Dnipro, according to Ukraine's state emergency service while another two were killed in the Chernihiv region.

Meanwhile, two British fighter jets were also scrambled from a base in Romania overnight after radar systems tracked drones near their airspace, according to the Romanian defence ministry.

"Two British Air Force Eurofighter Typhoon aircraft conducting Enhanced Air Policing mission scrambled at 02:00 from the 86th Air Base in Fetesti [Borcea Air Base]... The pilots were authorized to engage the drones," it said in a statement.

The Typhoons established radar contact with targets on Romania's eastern border with Ukraine, 1.5km from the Ukrainian city of Reni, the Romanians added.

At around 2.30am, an object was reported as falling in the Bariera Traian area of Romania, near the city of Galati, and drone fragments were later recovered.

Sky News understands RAF jets did not shoot them down or enter Ukrainian airspace.

"Practically all night, ‌the Russians bombed Dnipro and our other cities and communities," Ukrainian ​President Volodymyr Zelenskyy wrote on social media, adding that most of the targets were infrastructure.

He said there were also attacks in the Chernihiv, Odessa and Kharkiv regions.

Two bodies ​were recovered from a building in ⁠the southeastern city of Dnipro, regional governor Oleksandr Hanzha said, adding that five other people could ‌still be trapped in the rubble and another 21 people in the city were wounded.

In the ‌northern region of Chernihiv, missile and drone attacks killed two people and wounded seven others, while a further two people were wounded in the Odessa region, the respective local governors said.

Russian ‌forces ​also said they had captured the village of ​Bochkove ‌in Ukraine's ​northeastern Kharkiv region, the ​TASS ⁠state ⁠news agency ‌reported.

Russia has been launching ⁠smaller barrages of dozens of drones ​every night at Ukraine, interspersing them with occasional ​large-scale attacks that use hundreds of drones and dozens of missiles.

Meanwhile, in Russia, a woman was killed and a man was seriously wounded by a drone strike in the border region of Belgorod, local officials said. A Ukrainian drone also hit an apartment building in Yekaterinburg, injuring several people.

The attacks followed a prisoner swap Friday, in which Russia and Ukraine exchanged 193 service members.

Russian drones in Romania

Some damage was reported to an outbuilding and an electricity pole in Romania, but there were no injuries.

Drone fragments have routinely ​fallen on Romania, which has a 400-mile (650km) land border with Ukraine, as Russia repeatedly breaches its airspace.

"The defence ministry firmly condemns the ⁠irresponsible actions of the Russian Federation and emphasises that these represent a new challenge to regional security and stability in the ‌Black Sea area," the Romanian defence ministry's statement said.

Potential peace talks

Volodymyr Zelenskyy held talks ​in ‌Azerbaijan ​on Saturday ⁠with ‌his counterpart Ilham Aliyev to sign agreements on defence and energy co-operation.

Kyiv is seeking to strengthen its diplomatic and security alliances by offering its experience ​in countering drone attacks with low-cost methods.

According to the Kyiv Post, Mr Zelenskyy spoke after his meeting about the potential for peace talks with Russia in Azerbaijan.

"It is very important for Ukraine that Russia find the strength to end this unjust war. We certainly highly value the role of our partners in mediating this process.

"We told the president of Azerbaijan that we are ready for trilateral talks. We had such talks in Turkey, and we had such talks with our American partners in Switzerland," Mr Zelenskyy said.
