MP Eric Joyce arrested over assault at House of Commons bar A spokesman from the Metropolitan Police said: "We were called at about 10.50pm to reports of a disturbance at a bar at the House of Commons. A man in his 50s was arrested and was taken to a central London police station. Mr Joyce has had a colourful career, leaving the army in 1999 after criticising the force in a pamphlet for the Fabian Society. He was later elected for Falkirk West in a by-election. In 2009, it emerged he was Britain's most expensive member of Parliament after claiming £187,334 in expenses in 2007/08. Last year, he became the first MP to claim more than £200,000 in expenses in one year.
