The row over cuts to welfare benefits has rocked the Government to its core. Iain Duncan Smith resigned, attacking his own department's plans to cut disability benefits as balancing the books on the back of the poor and vulnerable. George Osborne has backed down; the cuts have now been put on ice. But the new benefit that prompted the row - Personal Independence Payment - is still going ahead. Hundreds of thousands of disabled people are now having to apply for this new benefit and many claim it is deeply unfair. Former Paralympian Ade Adepitan investigates and, using secretly recorded material, reveals some disturbing sides to the new benefit.
