Donald Trump has vowed that he'll do 'whatever I can' to end the conflict in Ukraine as world leaders agreed on Tuesday that Russia is not winning the war.

Ukrainian president Volodymyr Zelensky said G7 leaders including the US president agreed that the tide has turned and Moscow is losing ground in its illegal war.

Mr Trump called on Vladimir Putin to 'make a deal' as he said that he held a 'very good meeting' with Mr Zelensky, with whom he has previously had a rocky relationship.

Meanwhile Prime Minister Sir Keir Starmer told reporters at the leaders' summit in France that there has been a 'mood change' in Russia and that Moscow knows it is losing ground.

Mr Zelensky urged Mr Trump to open negotiations on new missiles to 'crank up the pressure' on Putin as he said that Russia 'must come to learn that its war will never be normalised'.

'I'm gonna do whatever I can,' Mr Trump said at the G7 summit in Evian-les-Bains, France, on Tuesday, adding that 'Russia should make a deal'.

The US president said: 'Russia's lost tremendous amounts of people, and so has Ukraine. Last month, they lost 35,000 soldiers between the two - it's on a monthly basis.

'They averaged 25,000 people, mostly soldiers, young, beautiful people, and it's crazy what's going on there.'

And with an agreement signed between the US and Iran over a peace deal, Mr Zelensky sensed a moment of opportunity for a deal over the war in Ukraine.

The Ukrainian president said that the G7 leaders unanimously agreed that 'Russia is not winning and losing a lot of people, and they have to make a deal as quick as possible'.

He added that a growing number of Russians understand they are not winning and should end the war 'better late than never'.

It came as Prime Minister Sir Keir Starmer told reporters at the G7 summit in France that there has been a 'mood change' on Ukraine in recent weeks.

He said: 'I want just to reflect real unity in the G7 on Ukraine, a real sense that things are changing, that Ukraine is now taking territory, which it has done over the last few months, rather than defending territory.'

Sir Keir added: 'The mood in Moscow is changing, and that was reflected around the G7 table in a pretty united way today.'

The Prime Minister and Mr Zelensky also held a bilateral meeting at the leaders' summit on Tuesday in which they discussed Ukraine's 'momentum on the battlefield'.

A Downing Street spokeswoman said of the meeting: 'It was clear there was a collective resolve to put pressure on Putin, both leaders agreed.

'It was now vital G7 countries gave Ukraine the support it needed to continue its success in driving back Russian forces, the Prime Minister added.'
