A "stupendously incompetent" government efficiency drive designed to save £57m has left taxpayers with an £81m bill, a report by MPs says.  The Department for Transport scheme aimed to cut administration costs by basing payroll, finance and personnel services all on one site in Swansea. But the public accounts committee said it had started late, had not been fully introduced and was set to make losses.The computer system had even issued messages in German, the MPs added. Edward Leigh, the committee's Conservative chairman, said it was one of the worst cases of "project management" the committee had ever seen.
