Spring cleaning at 10 Downing...Prime Minister Tony Blair fired his law and order chief and chose a new foreign secretary on Friday, trying to restore public support in his troubled government after his Labour Party took a pounding in local elections. Home Secretary Charles Clarke, embroiled in a politically damaging furore over the failure to deport foreign criminals, confirmed that Blair had removed him from office. Blair removed Jack Straw as foreign secretary, replacing him with Margaret Beckett, who had headed the Department of Environment, Food and Rural Affairs. Blair's office said Deputy Prime Minister John Prescott, who admitted an affair with a secretary, will keep his title. News reports said Foreign Secretary Jack Straw had been transferred to a new position.
