Andy Burnham took charge as fresh Labour chief on 17 July 2026.
He succeeded Keir Starmer following his victory in the contest.
Burnham called on his movement to stick together and championed what he branded ‘new politics’ in his address.
News reports described it as last piece of his long climb towards 10 Downing Street.
His win ensued following weeks of canvassing when Starmer resigned in spring.
