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 Saturday that the UK should rejoin the bloc “one day.” Streeting resigned as health secretary last week, saying he had lost confidence in Starmer.
