Today, British Prime Minister Boris Johnson is suffering from the biggest crisis in his leadership, particularly after being fined for the Partygate scandal, where he and his colleagues attended parties despite lockdown measures in the UK.

Despite the British government's successful launching of a successful COVID-19 vaccination program, around 12 of Johnson's Conservative MPs have expressed waning support for their elected Prime Minister over Partygate. 

There was "a moral vacuum at the heart of our government," wrote Tory MP Andrew Bridgen, who was a Johnson loyalist. 

Johnson, after weeks of denials and avoidance, apologized for one event that he attended in May 2020 at a time when citizens were barred from mobility. 

Downing Street, furthermore, apologized to Buckingham Palace for holding parties at a time when Queen Elizabeth II was preparing to bury Prince Philip, her husband of 73 years, calling the incident "deeply regrettable".

Johnson apologizes, but is he really sorry?

On Tuesday, Johnson revealed that he has been fined for breaking COVID-19 lockdown rules, apologizing for not following his own laws.

He posted a video online via Sky News, saying "I have paid the fine and I once again offer a full apology," claiming that it did not occur to him that he was breaking the law as he attended a "brief gathering" for his birthday in June 2020. 

"In all frankness, at that time it did not occur to me that this might have been a breach of the rules, but, of course, police have found otherwise," he said.

He maintained that he will not resign from his position despite calls for him to step down. The calls are from both Labor and Tories.
