Expenses test for Labour candidates
Gordon Brown has said that no MP who has defied the rules on their Commons expenses will be allowed to stand for election as a Labour Party candidate.
The Prime Minister also promised "major changes" in the system of MPs' expenses.
Meanwhile, Scotland Yard confirmed police will not investigate the leaking of details of MPs' allowances and expenses to a national newspaper because it was not considered to be in the public interest.
After addressing a meeting of Labour's ruling National Executive Committee, Mr Brown said that the expenses of every MP going back four years would be examined.
Mr Brown added: "If they are found to have broken the rules, then action will be taken."
Mr Brown also said that no MP who had broken expenses rules would serve in either the Cabinet or the Government.
He said: "I made it clear to the National Executive Committee today that no Member of Parliament or candidate will stand for the Labour Party if they have defied the rules."
Mr Brown added that he would be putting forward proposals for a "fundamental rethink" of the system.
Labour is setting up a process to examine all of its MPs' expense claims over the past four years, said Mr Brown. "If they have been found to have broken the rules, then action will be taken," he promised.
He said the cases of Elliot Morley and David Chaytor, who received expenses to cover mortgage interest payments after the loans in question had been paid off, were being considered by the NEC and the two MPs continued to be suspended from the Parliamentary Labour Party.
