His rival Penny Mordaunt chickened out
Rishi Sunak will now be the UK's next prime minister.
This comes after winning the Conservative Party leadership contest.
He will become the UK's first British-Asian PM and at 42, the youngest in more than a century.
The ex-chancellor who oversaw the nation's finances during the Covid pandemic was the only contender to gain enough support from MPs.
His rival Penny Mordaunt dropped out of the race in the final minutes before nominations closed.
