Gordon Brown has been branded an 'unfaithful tart', a 'slut' and a 'slapper' by users of Mumsnet, a community website set up by mothers to give advice on parenting and family issues.

The Prime Minister has upset Mumsnet followers - the women he exasperated last year by refusing to reveal his favourite biscuit - by opting to go on a rival site.

His appearance on the Netmums site has provoked criticism from middle-class Mumsnet users, reports Times Online.

One mum, going by the name weegiemum, wrote: "The unfaithful tart - he's ours!", while MadameDefarge said simply: "slapper".

EllieMental joked: " I am so over him. He never called, he never wrote."

The leader's decision to do the Mother's Day chat is being seen as an attempt to woo back the core female vote, which research has shown that Labour is losing. (ANI)
