Boris Johnson has chosen 'political interest ahead of the public interest' by refusing to sack Dominic Cummings says Scotland's Nicola Sturgeon (who tried to resist sacking her own lockdown-busting adviser)

• She accused Mr Johnson of jeopardising public health messaging over adviser
• Scotland's ex-top medic breached guidance with two visits to her second home
• She was eventually forced to resign, and Sturgeon said Cummings should also

Nicola Sturgeon blasted Boris Johnson today for choosing 'political interest ahead of the public interest' by refusing to sack Dominic Cummings.

Scotland's First Minister accused Mr Johnson of jeopardising public health messaging by backing his political adviser over alleged repeated trips to Durham during the lockdown.

The First Minister drew comparisons between Mr Cummings' situation and that of Scotland's former chief medical officer Dr Catherine Calderwood, who breached the guidance with two visits to her second home.

Ms Sturgeon initially backed Dr Calderwood after the Scottish chief medical officer  issued an apology, but was later forced to resign after a public outcry. 

Ms Sturgeon told the BBC's Good Morning Scotland programme that Mr Cummings should leave his post or risk undermining people's trust that following the coronavirus guidance was a collective effort. 

'I'm very concerned and - I say this with a very heavy heart - I really do fear that Boris Johnson has decided to put political interest ahead of the public interest,' she told the radio station. 

'The consequences of that are potentially very serious.

'Trust in public health messaging is very important and arguably, as we go into the phases where we start to lift lockdown, that becomes even more important because we rely less on the letter of the law, and much more on guidance and appealing to people's good judgment.'

Asked about Mr Cummings driving from London to Durham with his young child and symptomatic wife, Ms Sturgeon said: 'I think there will be families up and down the length and breadth of the UK who have had these same dilemmas, but they stuck to the rules because the rules were the rules.

'Of course everybody sympathises with parents who are worried about children and how their children will be looked after if they fall ill, but he was not alone.

'I think that is the issue here, that others follow the rules with all of the difficulty and all of the agonising that has come with that.

'The sacrifices people have made in recent weeks - not seeing ill family members, not being with family members perhaps before he passed away, not being able to attend funerals - these are enormous sacrifices and everybody has had to make them.

'I think that has been important and getting a sense... that we are all in that together.'

The First Minister drew comparisons between Mr Cummings' situation and that of Scotland's former chief medical officer Catherine Calderwood, who breached the guidance with two visits to her second home.

Ms Sturgeon said she had to sack Dr Calderwood once it became clear that the public health message was being affected.

She said Dr Calderwood did not 'try to save her own skin at the expense of the public health message', and argued that the Prime Minister and his political adviser 'should probably now come to the same conclusion'.

'I didn't defend [Dr Calderwood's] breach of the guidelines, I didn't try to retrofit the guidance,' Ms Sturgeon added.

'She recognised she'd made a mistake and apologised. I made an argument to the public at that time that she'd made a mistake but her advice was so important, given what we were dealing with, that she should stay in office.

'But when it became clear to me that the public, understandably, were not prepared to accept that I judged that integrity of the public health message was more important and actually, to her great credit, so did Catherine Calderwood.'
