Nicola Sturgeon said Boris Johnson has been the only prime minister she has worked with who was “a disgrace to the office”.
Speaking at a panel event at the Edinburgh Fringe on Saturday afternoon, Ms Sturgeon had strong words for the outgoing prime minister.
She said: “I disagreed with David Cameron, I disagreed with Theresa May, I disagreed with Boris Johnson, but he’s the only one who’s actually disgraced the office of prime minister.
“The sooner he’s gone, the better.”
Ms Sturgeon said the idea that parties were taking place during the Covid-19 pandemic “blew her mind”.
“The idea that this could have happened while the rest of country was going through the horrors of it really blows my mind,” she told audience members.
“Parties themselves are bad enough, but it was the lying, frankly, and the constant attempt to shift the goalposts and the narrative.
“He was a disgrace, let’s be honest.”
Four prime ministers have been in Downing Street since Ms Sturgeon took office in 2014 and she joked to audience members she never thought she would “look back fondly” on Theresa May as prime minister.
“At the beginning of Covid, I thought, it would be far better to have Theresa May – she always knew her stuff. She knew her brief,” Ms Sturgeon said.
She joked that Ms May was a “better dancer than I am”.
The first minister called for more diversity in politics and praised Scottish Labour for having diverse leaders.
She added: “Here’s a sentence you’ll never hear me utter before: to be fair to Labour in Scotland, they’ve already had a woman leader and they’ve currently got a Muslim leader so UK Labour really has to get its act together on diversity.”
When asked who she would prefer to see as prime minister, Ms Sturgeon shrugged and laughed and said none of them will win an election in Scotland.
She said: “It’s not really about that. They will never win an election in Scotland. What do Margaret Thatcher, John Major, David Cameron, Theresa May and Boris Johnson all have in common? They have never won an election in Scotland.”
She branded the choices facing voters in England as “terrible” and accused Labour leader Sir Keir Starmer of being “a pale imitation of the Tories”.
Ms Sturgeon also addressed comments made by Tory leadership contender Liz Truss who said she should be “ignored”.
She said: “I am the democratically elected first minister and you can only be in that position if a significant amount of people vote for you.
“When she said I should be ignored, what a lot of people in Scotland hear is the democratic votes and choices of people in Scotland should be ignored.
“I don’t think that’s appropriate.
“People in Scotland are getting increasingly tired of being ignored by Tory prime ministers.”
Responding to Ms Truss’s remarks she was an attention seeker, Ms Sturgeon told audience members you had to be a bit of an attention seeker as a politician to get your policies noticed.
Ms Sturgeon also hit out at former leader of the Scottish Conservatives Ruth Davidson for entering the House of Lords.
She said: “Ruth decided to retire from politics but then it transpired she wasn’t really intending to retire from politics, she just wanted to continue without scrutiny and the tedious bit of having to put yourself forward for election.
“So all of the good bits of politics without the tough bit of getting elected. I don’t think that’s a particularly good thing to do.”
Ms Sturgeon took questions from some audience members who asked her if it was possible to have a “good-natured debate” about independence.
“Of course it’s possible to have a good natured, civilised debate about independence but that requires all of us involved in that,” she said.
“The only appropriate way to decide matters we disagree on is through democracy.”
