Boris Johnson's standing down as British Prime Minister, and is expected to make a statement today.
It's understood he'll remain in post until the Conservative Party's elected his successor over the summer.
His resignation follows the release of a letter from his new chancellor - telling him to 'go now'.
Nadhim Zahawi told his boss the situation was 'not sustainable'.
Prime Minister: this is not sustainable and it will only get worse: for you, for the Conservative Party and most importantly of all the country. You must do the right thing and go now. pic.twitter.com/F2iKT1PhvC

50 members of Mr Johnson's government had resigned within two days.
Among the latest were the Northern Ireland secretary Brandon Lewis and Michelle Donelan - who'd been appointed education secretary just 36 hours beforehand.
A decent and responsible Government relies on honesty, integrity and mutual respect - it is a matter of profound personal regret that I must leave Government as I no longer believe those values are being upheld.

The mass rebellion began on Tuesday, when Downing Street admitted the PM knew about allegations of inappropriate behaviour against Chris Pincher - before he promoted him to deputy chief whip.
