Prime minister tells a summit of 29 leaders that the Russian president cannot delay peace talks indefinitely

Keir Starmer accused Vladimir Putin of dragging his feet over agreeing to a ceasefire with Ukraine on Saturday as international pressure grew on the Russian president to enter talks.

The prime minister said there was a limit to the length of time Putin could prevaricate, after he convened a virtual summit with 29 other international leaders who agreed to take plans for a peacekeeping force to an “operational phase”.
