Allen & Overy (A&O) has questioned aspects of allegations made by The Guardian that the law firm was “conned” into handing over client files while acting for Gordon Brown, as claims continue to emerge in the phone-hacking scandal.

An article published Monday (July 11) on the guardian.co.uk website alleged that the law firm was tricked into handing over details from the former Prime Minister’s file by a conman working for a prominent newspaper, and also described A&O as Brown’s “London lawyers,” a claim which has since been amended.
