LONDON (AP) " Rivals and allies paid tribute Monday to former British Prime Minister Gordon Brown, who plans to step down from Parliament at a national election in May.
Prime Minister David Cameron said Brown has "given a huge amount in terms of public service and his contribution in government and in Parliament."
Brown is due to make a speech Monday evening in his home town of Kirkcaldy, Scotland. British media say he will announce he is leaving Parliament after 32 years.
Brown, 63, served as Treasury chief under Labour Prime Minister Tony Blair for a decade from 1997, becoming prime minister when Blair stepped down in 2007.
He won praise for his handling of the 2008 financial crisis, but his premiership was dogged by gaffes and he failed to win the 2010 election, which produced a Conservative-Liberal Democrat coalition government.
