See Ross Parry copy RPYHILL A man who claimed he was so disabled he could barely walk has been busted as a BENEFIT CHEAT after being spotted working at the top of a historic peak. Graham Maughan, 48, has volunteered at the National Trust for three years – working at the iconic Penshaw Monument which is only accessible by a steep climb including 78 steps. However, throughout that time, Maughan pocketed over £8,000 in disability living allowance (DLA) at the highest mobility rate.
