He promised to fix a broken Britain. Now his own party has forced him out.

Prime minister Keir Starmer announced his departure on Monday after losing the support of his own lawmakers.

When leaders promise quick change, the clock starts ticking right away. For a country tired of broken promises, the hope of a new start can turn into anger in a flash.

WHAT HAPPENED

Keir Starmer said on Monday he will step down as prime minister of the United Kingdom. He told the public he will stay in office until his Labour Party picks a new leader.

The choice of a new leader will begin on July 9. Starmer expects the new prime minister to take over by September.

His decision comes after his party lost more than 1,000 local council seats in May. Many of his own lawmakers wrote letters asking him to leave.

WHAT THE ELECTION SHOWS

1,000: The number of local council seats the Labour party lost in May elections.

• 14: The number of years the Conservative Party ruled before Starmer won in 2024.
• 7: The number of prime ministers the UK will have had in ten years.
• 2: The number of years Starmer served as prime minister.

THE BIGGER QUESTION

Why does Britain go through leaders so quickly now? Voters want fast fixes for deep problems, but big changes take time.

When leaders cannot deliver right away, their own parties panic. They push them out to save their own jobs.

THE OTHER SIDE

Some supporters say Starmer did not get a fair chance. They point out that he won a massive victory just two years ago and kept Europe safe.

Still, the loss of 1,000 local seats shows that voters had already lost faith in his plan.

WHAT HAPPENS NOW

The Labour Party will choose a new leader this summer. Lawmakers are already backing Andy Burnham, the former mayor of Greater Manchester, to take the job.

Regular people in the UK must wait once again to see who will run their country.

WHAT WE STILL DON'T KNOW

Who will win the vote to become the next prime minister?

• Will the next leader change the main plans of the government?
• Can any new leader stay in power long enough to fix the country?
