A timeline of Johnson's career, from Brexit to Partygate

LONDON -- He was London's mayor, who revelled in hosting the 2012 London Olympics. And he was also the man who led Conservatives to a crushing election victory thanks to his pledge to "get Brexit done."

Boris Johnson's tenure as prime minister was marred by the handling of the coronavirus epidemic and a steady stream ethics allegations. These ranged from how he handled an alcohol-fueled government party that violated lockdown rules to his handling of a sexual misconduct case involving a senior lawmaker.

Here's a timeline that relates to Johnson's political career.
