She spoke as MPs were today approving the creation of a cross-party Speaker's Conference, the first for more than two decades, to look at ways to boost the number of women and ethnic minorities being elected. Ms Harman also wants it to examine issues such as the sexuality of MPs. She said: "We cannot sensibly discuss the veil (in the Commons) when there is no Muslim woman MP; it was impossible to discuss domestic violence when there was 97 per cent men in the Commons."
