Boris Johnson has agreed to resign this morning after a crisis in the Conservative party saw swathes of ministers quit his government.
He is due to make a statement outside No 10. later today confirming he will be stepping down amid calls from some of the most senior members of the party that it was time for him to go.
But after being elected with a huge mandate in 2019, and having successfully negotiated the UK out of the European Union, why has he chosen to end his term as Prime Minister early?
