Nigel Farage, the leader of Britain's right-wing Reform U.K. party, said the eastward of expansion of the European Union and NATO had provoked Russian President Vladimir Putin's invasion of Ukraine.

The remarks, made in an interview with the BBC aired late on Friday, drew strong criticism across the British political spectrum ahead of a July 4 election in which Farage's party is predicted to win millions of votes.

Farage said he stood by comments made shortly after Moscow's February 2022 invasion of Ukraine, when he posted on social media that the move was a "consequence of EU and NATO expansion."
