Rishi Sunak and Volodymyr Zelensky have held talks on ramping up military support as Vladimir Putin's troops launch a bloody new offensive.
The PM told the Ukrainian president that Britain and its allies "needed to continue to ensure Ukraine was in the strongest possible position to build on its recent battlefield successes".
They spoke this morning as the Ministry of Defence warned Ukrainian soldiers were being bombarded with "particularly intense" Russian artillery fire in the highly-contested city of Bakhmut.
