Plans for the UK and other European countries to send troops to Ukraine are in their very early stages. But the UK prime minister, Keir Starmer, will already be thinking about how such a move could play out at home. Sending UK troops abroad, even on a “peacekeeping” mission, always has the potential to spark huge public debate.

U.K. Prime Minister Keir Starmer says he's willing to send peacekeeping troops to Ukraine to maintain peace when the war with Russia ends.

Sir Keir Starmer is proposing a plan that includes deploying to 30,000 British and European troops to Ukraine to try to deter future attacks by Vladimir Putin.

The Kremlin said on Thursday that any British plan to send troops to Ukraine as part of a potential peacekeeping mission would be unacceptable for Russia and that it was monitoring statements by British Prime Minister Keir Starmer with concern.
