LONDON (AFP) - British Prime Minister Gordon Brown will appear before the public inquiry into the Iraq war in early March, a spokesman for the probe said Tuesday. Brown was finance minister at the time of the 2003 US-led invasion, and is being called to give his account of the conflict several weeks after then prime minister Tony Blair gave his long-awaited evidence on January 29. Inquiry chairman John Chilcot initially said he would not call Brown or any other serving ministers until after the general election, which must be held by early June at the latest, to avoid it dominating the political campaigns. But following pressure from opposition parties, Brown wrote to Chilcot saying he was happy to appear at any time. Organisers said they would hold a ballot for seats in the public gallery due to the anticipated high demand for places, as they did for Blairs session. The specific date for Mr. Browns session will be announced soon, but to help people decide whether they wish to take part in the ballot the inquiry has confirmed that it will be in early March, a spokesman said. A third of the places in the 60-seat hearing room in central London will be reserved for families of the 179 British military personnel who died in the conflict, the spokesman added. Foreign Secretary David Miliband and International Development Secretary Douglas Alexander are due to appear in a few weeks time, Chilcot said Monday. Since November, a succession of military chiefs, civil servants and former ministers have been called to explain Britains role in the invasion of Iraq in March 2003 and its aftermath. Blair has been the highlight of the inquiry so far but the appearance of Brown just weeks before the election, which many commentators expect to be on May 6, is likely to be political dynamite. The prime minister has until now said little of his role in the run-up to the war, which remains deeply divisive here and is viewed by many voters as a major mark against the Labour governments 13 years in office. Summing up the inquirys progress so far, Chilcot said Monday that the five-member panel has broken new ground and expected to complete its report by the end of the year.
