Sean Clerkin, of the Scottish Resistance, was protesting outside SNP conference yesterday.
James Scott, founder of the Scottish Resistance, said a meeting of the group had agreed the banner was “not acceptable” and should instead have read: “Westminster out of Scotland”.
He added: “Clerkin getting no support for this from the Scottish Resistance decided to go ahead with it any way. When we make a banner we put our name on it.
“We would like to make it very clear that this banner has absolutely nothing to do with The Scottish Resistance.”
