NICOLA Sturgeon has hit out at Scottish Tory leader Jackson Carlaw for refusing to criticise the PM's decision to defend Dominic Cummings for breaching lockdown rules.

The FM said Carlaw's statement was "strangely different" to his view on Catherine Calderwood who had to resign after travelling to her second home in Fife.

The PM told the daily Downing Street briefing that his top aide "acted responsibly, legally and with integrity" when he travelled more than 250 miles to his parents' home during lockdown. 

Johnson also said that “some” of the allegations about Dominic Cummings’ behaviour during self-isolation were “palpably false”.

After the briefing, Carlaw said: "I've heard what the Prime Minister has said and it is a situation for him to judge.“He has reached a conclusion and we must all now focus on continuing to beat this dreadful pandemic.

“I want the Prime Minister to be able to continue his excellent work leading the country out of lockdown and I am glad he set out his plans clearly today."

He added: "Here in Scotland, our focus must be on tackling the ongoing crisis in our care homes and building a robust testing and tracing system.

“There are more worrying reports today that this is proving difficult, and the Scottish Conservative focus will be on challenging the Scottish Government and demanding that promises both to protect care homes and isolate the disease are kept.”

Sturgeon tweeted: "Strangely different to his view on Cath Calderwood. Leadership is saying/doing the right thing even when it’s tough for you - not just calling for it when it’s tough for your opponent."

The FM previously called for Cummings to be sacked, saying "integrity of vital public health advice" is the most important thing.

She said: "I know it is tough to lose a trusted adviser at the height of crisis, but when it’s a choice of that or integrity of vital public health advice, the latter must come first. That’s the judgment I and, to her credit, Catherine Calderwood reached. PM and Cummings should do likewise."
