NICOLA Sturgeon described Douglas Ross as a "charmer" after it appeared the Scottish Tory leader aimed a dig at the First Minister.

Responding to questions around the Scottish Government's coronavirus response, Sturgeon took questions from opposition party leaders and then moved on to those from other MSPs.

The First Minister was asked a question by SNP MSP for Dundee City West Joe Fitzpatrick to provide assurances to businesses about the potential widening the use of Covid vaccine certification in more sectors.

Fitzpatrick said: "Can I ask the First Minister to provide an assurance that, should it be deemed necessary to introduce further measures such as an extension of mitigations or vaccine certification, to avoid the kinds of restrictions we've seen in Austria and the Netherlands, that this will be done with as much notice as possible with guidance for venues to support the implementation and continued engagement with affected sectors to understand the impact of any changes."

Before the First Minister gave her answer, talking could be heard from elsewhere in the chamber which she picked up as she looked incredulously towards the Scottish Tory benches and sighed before appearing to repeat what was said: "Not with her."

Looking towards presiding officer Alison Johnstone she then added: "He's a charmer, is the leader of the opposition."

The two party leaders had clashed previously in the FM's Covid update where Sturgeon announced that vaccine certificates may be extended to more areas.

A decision is to be made by the Scottish Cabinet next week and ministers will consider whether the extension would be “justified and prudent”.

Ross criticised the FM's announcement, saying that the public were expecting a statement that delivered "clear decisions".

He said that businesses were being "left in the dark" and suggested they might not have enough time to implement vaccine certifications.

Sturgeon hit back, saying that "the immaturity and irresponsibility of Douglas Ross in the face of a virus continue to be utterly breathtaking".

She accused the Scottish Tory leader of opposing any policy the Scottish Government put forward on Covid, regardless of how effective it is.
