As a former Equalities Minister who was dedicated to helping minority groups, Harriet Harman perhaps should have known better.
But in an outspoken attack, the Labour Deputy Leader yesterday called Danny Alexander a "ginger rodent".
Speaking to the conference in Oban, she also said the Lib Dems in Scotland had become "political mutants" after joining a coalition with Conservatives.
Ms Harman began her attack saying people had been dismayed after the election to wake up and see "Nick Clegg with David Cameron in the rose garden of Number 10".
She said there was then "incredulity" at seeing Mr Alexander, an MP from the north of Scotland, becoming "the frontman for the Tory cuts".
"Now, many of us in the Labour Party are conservationists and we all love the red squirrel," Ms Harman said. "But there is one ginger rodent which we never want to see again in the Highlands – Danny Alexander." >>> Melissa Kite | Saturday, October 30, 2010
