A Labour leadership hopeful has placed the possibility of undoing Brexit high on the political​ agenda in an expected contest to oust British Prime Minister Keir Starmer.

Prompting accusations that Labour is preparing for a Brexit “betrayal,” Wes Streeting said on May 16 that the UK should rejoin the bloc “one day.” Streeting resigned as health secretary on May 14, saying that he had lost confidence in Starmer.
