A meeting of the National Security Advisers will be held in the UK and hosted by Foreign Secretary David Lammy and US Vice President JD Vance.
It will take place at Chevening, Lammy's official country residence in Kent where Vance is staying as part of his holiday in the UK.
The aim of the meeting is to bring together advisors from the US, Europe and Ukraine - it is understood to have been requested by the US.
A Downing Street spokesperson said that Keir Starmer and Volodymyr Zelensky agreed the meeting would be a 'vital forum to discuss progress towards securing a just and lasting peace'.
'Both leaders welcomed President Trump's desire to bring this barbaric war to an end and agreed that we must keep up the pressure on Putin to end his illegal war,' the spokesperson added.
