British Prime Minister Boris Johnson was fighting to shore up his premiership on Wednesday amid a revolt by his own lawmakers who are angry over a series of lockdown parties in Downing Street.

Propelled into the top job to "get Brexit done", Johnson in 2019 won his party's biggest majority in more than 30 years but now faces calls to resign after a series of revelations about parties in Downing Street - the prime ministers' home and office - during Covid lockdowns.
