Harman also commissioned a report on allowing political parties to draw up all-black shortlists designed to increase the number of black MPs in Westminster. A further report proposed extended the arrangement allowing all-women shortlists beyond 2015 which will fail to have any impact in the 2010 general election. These proposals are supported by members of the three major parties, though no others allow discrimination in their shortlists. Inside the Labour Party, Harman has said she does "not agree with all-male leaderships" because men "cannot be left to run things on their own"; and that, consequently, one of Labour's top two posts should always be held by a woman. She had also stated that the collapse of Lehman Brothers might have been averted had it been 'Lehman Sisters'. These comments caused accusations of sexism and "insidious bigotry".
