UK's Starmer welcomes Ukraine ceasefire proposal, says ball is in Russia's court

LONDON, March 11 (Reuters) - British Prime Minister Keir Starmer welcomed on Tuesday a 30-day ceasefire proposal that Ukraine has agreed to and said it was now up to Russia to end the fighting.

"As both American and Ukrainian delegations have said, the ball is now in the Russian court," Starmer said in a statement, congratulating both Ukrainian President Volodymyr Zelenskiy and U.S. President Donald Trump for the "remarkable breakthrough".

Starmer said he would use a meeting of world leaders that Britain is convening on Saturday to discuss next steps. "We are ready to help bring an end to this war in a just and permanent way that allows Ukraine to enjoy its freedom," he said.
