LONDON -- Boris Johnson has brought in new senior staffers as he tries to restore his flagging authority - including a communications chief who insisted the British prime minister is 鈥渘ot a total clown.鈥

The prime minister hired Guto Harri, an aide from his days as London mayor who has recently been critical of Johnson, to try to regain control of the government's messaging after weeks of turmoil that have led some in the ruling Conservatives to call for his removal. He also appointed a senior Cabinet minister, Steve Barclay, as his new chief of staff.

But unease about Johnson's leadership grew Monday when opposition Labour Party leader Keir Starmer was harassed outside Parliament by anti-lockdown protesters who accused him of protecting pedophiles when he was a prosecutor - echoing a slur made by Johnson last week.

Visiting a hospital cancer center Monday outside London, Johnson said he was 鈥渇ocused completely鈥 on clearing a backlog of millions of medical procedures built up during the pandemic. It's one of a pile of critical issues, including a squeeze on household finances from inflation and a looming tax hike, that are being overshadowed by scandal over lockdown-breaching government parties.

鈥淚 think what people want is for the government to focus, not on stuff going on at (the government district of) Westminster, but to focus on life ... beyond Westminster, and to focus on the needs of the country,鈥 Johnson said. 鈥淎nd that is what we're doing.鈥

Johnson's grip on power has been shaken by public anger over revelations that his staff held 鈥渂ring your own booze鈥 office parties, birthday celebrations and 鈥渨ine time Fridays鈥 in 2020 and 2021 while millions in Britain were barred from meeting with friends and family because of his government's COVID-19 restrictions.

A total of 16 parties have been investigated by a senior civil servant, Sue Gray, with a dozen of them also under investigation by the Metropolitan Police.

In an interim report last week into the four parties not under criminal investigation, Gray found that 鈥渇ailures of leadership and judgment鈥 enabled events to occur that 鈥渟hould not have been allowed to take place鈥 and described a Downing Street operation marked by excessive drinking and dysfunctional dynamics.

Johnson apologized -- without admitting personal wrongdoing -- and pledged to fix the problems in his office.

But on Friday he was rocked by the departure of five senior staff, including his chief of staff, his communications director and his policy director, Munira Mirza. Mirza, a loyal longtime aide, stood by the prime minister amid the 鈥減artygate鈥 revelations. But she said the final straw was Johnson's 鈥渟currilous accusation鈥 that Starmer had failed to prosecute the late pedophile Jimmy Savile for sexual abuse when Starmer was the U.K.'s director of public prosecutions.

On Monday, Starmer was surrounded outside Parliament by protesters against coronavirus restrictions. They could be heard yelling 鈥淭raitor!鈥, mentioning Savile and throwing accusations of 鈥減rotecting pedophiles.鈥 Starmer was driven away in a police car. Police said two people were arrested.

Johnson called the harassment 鈥渁bsolutely disgraceful,鈥 but some said he should take responsibility. Julian Smith, a former minister in Johnson's government, tweeted that 鈥渢he false Savile slurs鈥 must be 鈥渨ithdrawn in full.鈥

Johnson responded to recent weeks' turmoil with a Downing Street shakeup that included the eye-catching appointment of Harri, a former BBC journalist who worked for Johnson at City Hall from 2008 to 2012 but has more recently criticized him. In 2018, Harri called Johnson 鈥渟exually incontinent,鈥 and in 2020 he said government communications during the pandemic had been 鈥渁 masterclass in incompetence.鈥 Last month Harri said reports of parties in Downing Street while Britain was in lockdown were 鈥渦nforgivable,鈥 though also 鈥渦nderstandable in some ways.鈥

Harri told a Welsh-language news site that Johnson greeted him on his first day by singing Gloria Gaynor's disco anthem 鈥淚 Will Survive.鈥

Harri, who is Welsh, told the Golwg360 site that Johnson was 鈥渘ot a total clown,鈥 but in fact 鈥渁 very likeable character.鈥

He said the prime minister is 鈥渘ot the devilish man as some wrongly portray him to be.鈥

The staff moves are intended to reassure Conservative lawmakers who are debating whether to seek a no-confidence vote in the leader who won them a big parliamentary majority just over two years ago.

Under party rules, a no-confidence vote is triggered if 15% of party lawmakers - currently 54 people - write letters calling for one. If Johnson lost such a vote, he would be replaced as party leader and prime minister.

Only 15 of the 360 Conservative legislators have publicly called for Johnson to quit, though the number who have written letters is likely higher.

Conservative lawmaker Tom Tugendhat, who has already said he will run for leader if Johnson is ousted, said the prime minister's fate depended on 鈥渉ow the reset goes.鈥

He said 鈥渢here's an awful lot of talent going in,鈥 but also 鈥渁n awful lot of talent coming out.鈥
