A UK Treasury Minister has resigned after reports that she avoided paying almost 20 thousand euros in capital gains tax on the sale of one of her two homes. Kitty Ussher denied any wrongdoing but said she was stepping down to save Prime Minister Gordon Brown’s government further embarrassment.Members of Parliament from all parties have been under pressure following revelations of expense claims ranging from glitter toilet seats and moat cleaning to the rental of pornographic films. Ussher’s departure is another blow for Brown, who is trying to reassert his authority after a series of serious setbacks. Eleven of his ministers have left the government, and the party suffered a resounding defeat in the recent European elections. Brown’s leadership has also come under question from within the Labour Party itself.
