THE leader of the Scottish Conservatives has been branded a "f*****g w*****r" during a live Channel 4 interview.

Douglas Ross continued to speak as a car horn was blared and he was heckled while filming with Channel 4 news on Wednesday evening, following Nicola Sturgeon's appearance at the UK Covid Inquiry.

The Tory MP and MSP had been making comments about the reported concern among figures in the Scottish Government during Covid on whether the Spanish government would block entry to the EU were the country to become independent, dependent on pandemic measures put in place at the time.

As he spoke in Edinburgh, a loud horn was blared from a passing car and someone shouted "f*****g w*****r" from their window.

Channel 4 quickly apologised for the "foul language" and Ross smiled.

One social media user shared the clip, writing: "God bless whoever just called Douglas Ross a f*****g w*****r live on C4 news".

During Sturgeon's appearance at the inquiry, she had rejected politicisation of the pandemic and said she had never thought about the idea of Scottish independence less.

Jamie Dawson KC brought up minutes of a Cabinet meeting, which said ministers had “agreed that consideration should be given to restarting work on independence and a referendum, with the arguments reflecting the experience of the coronavirus crisis and developments on EU Exit”.

Dawson asked Sturgeon if the document showed Scottish ministers had looked “to promote the cause of Scottish independence by politicising the pandemic”.

Responding, the former SNP leader said: “No, I respectfully don't think that is a fair or accurate reading of that.”

She added: “We agreed that consideration should be given to restarting work [on independence. In matter of fact, work did not restart. It was not consideration that led to that happening.

“That is the fact of the matter … In my mind, there was no prospect of starting work on independence at that time.”
