British Prime Minister Boris Johnson faced renewed calls to resign on Monday after a report found that alcohol-fueled parties at his offices and residence when COVID-19 lockdown rules were in force should never have taken place.

The report by senior civil servant Sue Gray into the lockdown gatherings — at a time when Britons were all but banned from social mixing to tackle the coronavirus pandemic — pointed to "serious failures of leadership" at the heart of the British government.

She condemned some of the behavior in government as being "difficult to justify," saying "the excessive consumption of alcohol is not appropriate in a professional workplace at any time."
