Web post slammed as'sexist'.
Judith Tonner Airdrie & Shotts' SNP branch has been heavily criticised for a Facebook post describing the running of North Lanarkshire Council as a "comfy threesome".
It depicted a bed with the words: "The Conservatives and Labour aren't the only ones getting into bed with each other to control councils ... in Airdrie there is an independent making a comfy threesome"; and naming Conservative and Labour group leaders Meghan Gallacher and Jim Logue, and Airdrie North independent Alan Beveridge.
Councillor Gallacher said: "It's not attacking me for my policies or what I believe in - it's been made personal and it's unpleasant.
"If you disagree with me on ideology then say something about it, but never say something personal.
"It's not acceptable and could be seen as sexist. I'd like an apology and to make sure this doesn't happen to anyone else."
Councillor Beveridge - a former SNP member - hit out: "The image was in the main a petty and personal attack aimed squarely at me.
"I've repeatedly acted in the best interests of my constituents, and have voted against motions proposed by the Labour group or in support of motions by the SNP if I believe them to be the right thing to do."
SNP branch convener Michael Coyle apologised to Councillor Gallacher, saying: "It shouldn't have happened. I don't know how it was posted, but as soon as I found out I had it taken down.
"I'm issuing an apology and we'll be more stringent to make sure it doesn't happen again."
