Prime Minister Andy Burnham has said his task is to "repair bridges" between Ukraine and the United States ahead of a meeting with President Volodymyr Zelensky in Downing Street.

This comes after US President Donald Trump said he had reached an agreement with Moscow to import Russian diesel.

Asked about Trump's action during Prime Minister's Questions, Burnham resisted criticizing the US president, saying he wanted to be "careful about setting the stage for bringing people together".

However, he stressed that Zelenskiy would not leave the UK empty-handed, as he said more military and financial support would be provided in the coming weeks.

Burnham is expected to use the meeting to promise more sanctions against Russia, while announcing that Britain will speed up the delivery of its air defense missiles to Kiev.

Britain will also urge allies to increase pressure on Russia, with Chancellor John Haley using IMF meetings to call for a ban on Russian liquefied natural gas (LNG).

Liberal Democrat leader Sir Ed Davey asked during PMQ meetings whether he agreed the diesel deal was "another disgraceful betrayal by Trump of the people of Ukraine and the security of Europe".

In response, Burnham did not repeat Sir Ed's condemnation of Trump, saying: "What I have to do in my role is to mend bridges until the support comes back, and so at this point I have to be careful in terms of creating the ground for people to come back together."

The prime minister said he spoke to Zelenskiy by phone on Saturday "because I understand that this was another very dark and difficult moment for him, because they are thinking about a winter that will be difficult for his people."

Zelensky backs Trump's 'energy ceasefire' but says Russia will continue to attack power plants

The phone call came after Trump announced that Russian President Vladimir Putin had agreed to release millions of tons of Russian diesel to the United States as he suspended sanctions on diesel from Moscow.

Zelensky called the move a gift to Putin and warned that it would give Moscow money to continue its war against Ukraine.

"It's time for Ukraine to elect a new president," Trump responded.

On Sunday, the US president claimed that Russia and Ukraine had agreed to an immediate energy ceasefire - but hours later, Zelensky said Russian attacks on energy facilities continued.

On Monday, Russian Foreign Minister Sergei Lavrov said Ukraine did not deserve a "respite" from the ceasefire.

This is Zelenskiy's second visit to the UK since Burnham was prime minister. The first time was in late July, days after Burnham arrived at No. 10, when the couple met with soldiers and led a news conference at the naval base in Portsmouth.

Among the measures announced is to speed up the delivery of British light multi-purpose missiles (LMMs), of which the UK has already committed to sending more than 5,000 worth £1.6 billion over the next four years.
