'There will be a widespread sense of relief', Nicola Sturgeon on PM's resignation

First Minister Nicola Sturgeon says "there will be a widespread sense of relief" as Prime Minister Boris Johnson agrees to step down.

Ms Sturgeon also questioned how sustainable Mr Johnson carrying on in the role until October would be.

She tweeted: "There will be a widespread sense of relief that the chaos of the last few days (indeed months) will come to an end, though notion of Boris Johnson staying on as PM until autumn seems far from ideal, and surely not sustainable?

"Boris Johnson was always manifestly unfit to be PM and the Tories should never have elected him leader or sustained him in office for as long as they have.

"But the problems run much deeper than one individual.

"The Westminster system is broken."

Other Scottish politicians have also been reacting to the news. 

Scottish Labour Leader Anas Sarwar said that the country will "breathe a sigh of relief."

He added: "Let's not forget that whoever replaces him is complicit.

“This is a party that is rotten to the core, that allowed a cheat, a charlatan, a man devoid of any principles or any values to become the Prime Minister of this country -  and they inflicted his carnage on this country for years.

“That's why not only do we need to see the back of Boris Johnson, we also need to see the back of this Tory government.

 “And that's why we need an election to elect a Labour government that can bring the values of decency, integrity and principles back into our country.”

Former Scottish Tory Leader Baroness Ruth Davidson tweeted: "There's no way he can stay on until October. It's arrant nonsense to think he can. Someone needs to grip this."

SNP Westminster Leader Ian Blackford MP said: "Boris Johnson's resignation is welcome but for Scotland it changes very little – we’re still controlled by a Westminster system that saw fit to make him Prime Minister.

"Whoever replaces him, Scotland will still be saddled with a Tory government we didn't vote for imposing Brexit, austerity cuts and damaging policies against Scotland's will.

"And with all the Westminster parties fully signed up to a hard Brexit, it is clear a change of government alone cannot provide the real change that Scotland needs.

"The only way to escape the damage of Westminster control is to become an independent country, with the full powers needed to regain our place in Europe and build a fair and prosperous future.

"Whoever takes over from Boris Johnson must respect the democratic mandate Scotland has to hold an independence referendum so we can escape Westminster control for good."

MP for Edinburgh West Christine Jardine from the Scottish Liberal Democrats said: "It's been clear to most of the country for some time that Boris Johnson simply wasn't fit to be Prime Minister.

"And the voters, I don't think, will forgive the Conservative Party easily for propping him up in office for so long."
