Foreign secretary David Lammy said the UK and America “won’t be bullied” by the Russian president.
His comments came after Keir Starmer and US president Joe Biden failed to reach a deal which would see Ukraine given permission to fire British Storm Shadow missiles deep into Russia.
Speaking last week, Putin said that would “would mean that Nato countries, the United States, and European countries, are at war with Russia”.
Asked about the impasse on Sky News this morning, Lammy said: “We won’t be bullied by Putin’s shameless grandstandiung.
“What he should now do is cease his aggression and leave Ukraine, that’s what he should do.
“But the UK and our public should be absolutely confident that we are supporting Ukraine in their struggle.”
