Andy Burnham, mayor of Greater Manchester, is positioning himself to challenge Keir Starmer for Labour leadership and UK prime minister, with several potential paths to oust Starmer, including triggering a leadership contest or waiting for another candidate to do so.

• Andy Burnham, mayor of Greater Manchester, won a parliamentary seat, advancing his bid to challenge Keir Starmer for Labour leader and UK prime minister.
• Burnham could trigger a leadership contest by securing 20% of Labour MPs' support, requiring 81 lawmakers including himself, with a formal challenge needing to be announced before July 16.
• Another Labour politician, Wes Streeting, has indicated he might challenge Starmer if the prime minister does not outline his departure terms, with polls suggesting Burnham would win in a three-way contest.
