Andy Burnham is set to officially become the next prime minister on Monday, but a number of things have to happen before then. Here’s how everything is expected to play out.

As such, of the 12 prime ministers from 1945 until 2010, only Margaret Thatcher was dismissed by her party for overtly political reasons. Her backbenchers and her cabinet no longer believed she was an election winner, and she was unceremoniously dumped in 1990. She described it as “treachery with a smile on its face”.

British Prime Minister Keir Starmer announced he will resign after mounting pressure from within his own governing party

The next prime minister promised nothing less than the biggest change in British politics in 40 years in his first speech as Labour leader.

There won’t be a general election now because Labour has another three years before it must face voters and, more importantly, it is way behind in the polls. It would be political madness for Starmer’s successor to call an early vote. The more pressing question is whether there will even be an internal party leadership contest.
