The UK’s governing Labour Party was headed for a divisive battle over the country’s top political office, as a leading Cabinet member prepared to challenge Prime Minister Keir Starmer .
Allies of Wes Streeting , who hails from the right wing of the party, said on Wednesday that the health secretary was likely to quit his post this week and launch a bid to replace Starmer as Labour leader. The prime minister’s own supporters immediately affirmed his determination to contest any attempt to unseat him.
