Scottish Labour leader Kezia Dugdale has claimed she is being pursued for a £10,000 in damages by a pro-independence blogger.

Dugdale has revealed Stuart Campbell, who runs the Wings Over Scotland website, has sent her a letter accusing her of damaging his reputation.

The Labour leader revealed the apparent defamation bid at First Minister's Questions on Thursday.

In response to Dugdale's comments in the chamber, Mr Campbell called the politician a "galactic scale idiot" on Twitter.

Dugdale says the defamation claim focuses on a article penned by the Labour leader in the Daily Record which discussed a tweet sent by Mr Campbell.

Sent from the '@WingsScotland' account in March, the tweet concerned the Conservative MSP Oliver Mundell and his father, the Scottish secretary David Mundell.

It read: "Oliver Mundell is the sort of public speaker that makes you wish his dad had embraced his homosexuality sooner."

At First Minister's Questions on Thursday, Dugdale said: "In the Daily Record I called out Mr Campbell for his homophobic comment.

"Mr Campbell has written to me via his lawyer to demand a £10,000 payment for, and I quote, 'damage to reputation'.

"I stand firm to my comment. I have never kowtowed to a bully and I will not start today."

The Labour leader called on Nicola Sturgeon to condemn the pro-independence blogger.

The First Minister replied: "Of course I do. For Kezia Dugdale to get up here, and I am being serious about this, to suggest that in any way, shape or form that I would condone homophobia I think is deeply unfortunate."

She added later in the exchanges at Holyrood: "I am not responsible for Stuart Campbell any more than Kezia Dugdale is responsible for people who hurl abuse at me in the name of being a supporter of the Labour party."

Dugdale said it was time for the SNP leader to ensure her party "denounces and shuns" Mr Campbell and his website.

Sturgeon said some of the abuse she personally receives online would "make somebody's hair curl".

She suggested Dugdale's questions were a "political smokescreen" aimed at taking the spotlight away from Labour councillors being suspended for going into a coalition deal with the Conservatives in Aberdeen.
