Labour's pink minibus which it is using to attract female voters is "nonsense", a political opponent has said.
MPs including Ashfield representative Gloria de Piero are touring the UK ahead of the general election.
But Mike Buchanan, from the anti-feminist Justice for Men and Boys party, said: "Some people thought it was a joke at first, but it doesn't surprise me.
"They are the feminist party, the others are not far behind them. It's entirely consistent with their nonsense.
"I don't think we'll start driving round in a baby blue van encouraging people to vote for us. It's a lovely idea, if only funds allowed."
Harriet Harman said: "We want women to feel that this is their democracy and politics is for them as well as for men. Politics is too important to be left to be a men-only activity. We are saying this is a woman-to-woman activity."
