Volodymyr Zelensky and Rishi Sunak held a press conference on Wednesday evening as the Ukrainian President continued his historic visit to the UK.
The leaders took questions from reporters after meeting Ukrainian troops being trained by the British Army at a base in Dorset.
Mr Sunak told the joint press conference the UK's Challenger 2 tanks would be in operation in Ukraine by “next month”. He said the “sophisticated weapons” would “soon be making a difference on the battlefields of your country”.
Mr Zelensky said Kyiv’s relations with the UK have reached a “new level”.
"It is very clear that we are standing together with Great Britain,” he said.
Mr Zelensky and Mr Sunak arrived by helicopter at Lulworth Camp on the latest leg of the Ukraine leader’s whirlwind surprise visit.
Earlier, Mr Zelenszky was granted an audience with the King at Buckingham Palace.
The King said: “We've all been worried about you and thinking about your country for so long, I can't tell you.”
The audience followed Mr Zelensky’s address to Parliament, in which he urged the UK and the West to provide fighter jets as he told his audience: “Combat aircraft for Ukraine, wings for freedom.”
Mr Zelensky began his speech by thanking Britain on behalf of his country's “war heroes”.
He also thanked former prime minister Boris Johnson for the support he showed as Russia launched its invasion.
“London has stood with Kyiv since day one, from the first seconds and minutes of the full-scale war, Great Britain you extended your helping hand when the world had not yet come to understand how to react,” he said.
“Boris: you got others united when it seemed absolutely impossible. Thank you.”
Mr Zelensky earlier met Rishi Sunak at Number 10 after jetting in to Stansted airport for his surprise visit.
The war dominated Mr Sunak’s exchange with Sir Keir Starmer at Prime Minister’s Questions at midday.
