LONDON (Agencies) - The speaker of Britains House of Commons Michael Martin said Tuesday he will resign on June 21 following an uproar over lawmakers expenses. Since I came to this House 30 years ago, I have always felt that the House is at its best when it is united, Martin told the House of Commons in a statement lasting under a minute, just a day after being humiliated in the chamber by cross-party calls for his resignation. In order that unity can be maintained, I have decided that I will relinquish the office of speaker on Sunday, 21 June. That is all I have to say on this matter. The House of Commons will now elect a new speaker on June 22, he added. Martin, a former sheet metal worker and trade unionist from Glasgow, Scotland, had been under intense pressure from lawmakers who claimed he was an obstacle to reforming the parliamentary system in the wake of the expenses row. A total of 23 MPs from all sides of the political divide had signed a vote of no-confidence in him. Details of MPs claiming expenses from the public purse for everything from swimming pool and tennis court repairs to installing a chandelier have leaked out in the Daily Telegraph newspaper over the last 11 days. The revelations of lavish spending have provoked fury in recession-hit Britain and prompted Prime Minister Gordon Brown to apologise and pledge extensive changes to the system. It has emerged that former Tory minister Ann Widdecombe would be willing to stand as an interim Speaker before the election of Martins successor. His resignation came as it was announced that The Daily Telegraph will not face a police inquiry over the disclosure of MPs expenses. Speaker Martin has become the highest-profile victim of the Westminster MPs expenses scandal, which claimed another scalp today. Tory MP Douglas Hogg, ridiculed for claiming for his country house moat to be cleaned, announced he would not be standing in his Sleaford and North Hykeham constituency at the next election in the wake of the row. Gordon Brown, the Prime Minister, said later that no MP who had defied the rules on their Commons expenses would be allowed to stand for election as a Labour Party candidate. After addressing a meeting of Labours ruling National Executive Committee, the British Prime Minister also promised major changes in the system of MPs expenses. Speaker Martins position became untenable after he lost the support of MPs over his handling of their expenses system. On Tuesday a motion calling for his immediate resignation appeared on the Commons order paper signed by 23 MPs from across the political spectrum. Douglas Carswell, the Tory MP who tabled the motion, said he hoped Martins successor would have the moral authority to push through reforms that would restore dignity to politics. It gives me no pleasure to have done this at all, but it was necessary to do it. We need a new Speaker who understands that 'sovereignty of Parliament is shorthand for 'sovereignty of the people, he said. A Labour MP who has signed the no-confidence motion and clashed on Monday with Martin in the Commons welcomed the news of his imminent resignation. That is the right and honourable course to take. His resignation will be the first step in the House recovering its reputation, he said, David Winnick said. But Austin Mitchell, a Labour backbencher, described the treatment of Martin as a public humiliation and accused his opponents of being motivated by snobbery. Partly it is a class issue, he said. In astonishing scenes in the Commons on Monday, MPs ignored centuries of convention and openly argued with the Speaker as he struggled to get to grips with the crisis engulfing Westminster. Despite making an unprecedented apology to the country, Martins statement descended into chaos with MPs on all sides urging him to go. One veteran Tory MP likened the mood to that of the Norway debate in 1940 when Neville Chamberlain was urged: In the name of God, go.
