Leaked documents show A4e found "potential fraud" across its offices in 2009 A4e was subsequently handed a £440 million contract by the Government, extending its work to help jobless people get back into work. David Cameron, the Prime Minister, also appointed its chief executive, Emma Harrison, as his families tsar. Liam Byrne, the Shadow Work and Pensions Secretary, last night said Government "has now got a great deal of explaining to do." However, the Department for Work and Pensions insisted that it had been assured by the company at the time that there were no "major issues." A spokesman for A4e said its systems have now been improved since the internal review in 2009. "While this investigation uncovered a number of areas where procedures may have been lacking, the final audit and further investigation determined that five claims were irregular and related to one former employee," he said. This was reported to the DWP Risk Assurance Division, which confirmed that the action taken by A4e fully met their own audit requirements and that they considered the matter satisfactorily resolved. A4e repaid the value of these three claims in full, which totalled less than £5,000. Mrs Harrison resigned from the company and as a Downing Street adviser earlier this year, after it emerged the company is now at the centre of a police investigation. Yesterday, a fifth former employee of A4e was arrested by Thames Valley Police as part of its ongoing investigation.
