Britain's former Prime Minister Margaret Thatcher, left, arrives to a Remembrance Day ceremony to pay tribute to the war dead of Britain and the 54-nation Commonwealth at the Cenotaph in London's Whitehall, Sunday Nov. 13, 2005. The service is held on the nearest Sunday to the anniversary of the end of World War I on Nov. 11, 1918, and also honors those killed in subsequent conflicts, including almost 100 who have died in Iraq since the March 2003 invasion.
