A blogger accused of expressing "unacceptable" views on Twitter has appeared in a Better Together campaign video.

Yvonne Hama was featured in a referendum broadcast for the pro-Union campaign screened on 18 August.

Social media users claimed she had retweeted former BNP leader Nick Griffin and compared the SNP to Nazis.

Better Together had removed a blog post by Ms Hama from its website and called the views on Twitter "unacceptable".

Monday's campaign video is on YouTube but is restricted to private viewings by the owner.

A spokesman for Better Together said the online video was a "work in progress" version which had only been made available to the press ahead of Monday's broadcast, and was therefore restricted.

The spokesman confirmed that Ms Hama had appeared in Monday's broadcast version.

He added: "She has retweeted things that she has realised were unacceptable, and we acted quickly to take them down."

Ms Hama's article, entitled "Why I'm saying No Thanks", appeared on the Better Together website on Sunday but was inaccessible on Monday.

Her Twitter account also appeared to have been disabled.

Ms Hama, who described herself as a single mother from Airdrie, apparently sent a tweet to Deputy First Minister Nicola Sturgeon in January 2012, which read: "u will like borgen...german...#snp nazis ring a bell :)".

She was also alleged to have retweeted a message from former BNP leader Nick Griffin later in the same year which read: "Greetings to all Ulster friends on the 12th July. Also all in Southport. Have a great day & No Surrender!"

Ms Hama appeared to have tweeted a photograph of herself alongside Better Together head Alistair Darling at an event on Saturday.

The text alongside the photograph read: "Was honoured to speak at the better together event in coatbridge alongside @TogetherDarling #indyref."

Both sides of the independence debate have attempted to distance themselves from supporters who post abuse on social media.

In June, Harry Potter author JK Rowling was the target of abuse after she donated £1m to the pro-UK campaign.

And pro-Union campaigner Clare Lally described being subjected to "disgraceful, shocking and disgusting" abuse by what she described as "keyboard warriors" after false information was posted about her on a nationalist website.
