How much women are in the british parliament?

As of March 2013, there are 146 female Members of Parliament compared to 504 male Members of Parliament. Of these women, 86 (of 255) represent the Labour Party, 47 (of 303) the Conservative Party and 7 (of 57) the Liberal Democrats. The Scottish National Party and the Socialist Democratic and Labour Party both have a single female MP out of three each.

There are two parties represented exclusively by women: both the Green Party of England and Wales and the Alliance have a single MP, in both cases a woman. Additionally, Sylvia Hermon (former Ulster Unionist Party) sits in the House as an independent MP for North Down.

The 146th female Member of Parliament, Michelle Gildernew, was elected in 2010 for her third term as a Sinn Fein MP (of 5). Sinn Fein candidates however do not take up their seats in the House of Commons and thus she has never attended, or voted in, any parliamentary session during her 12 years as a member.
