The DWP get it right most of the time but there are a few horror stories that crop up when things go wrong. For instance, one of Aggies Bingo Buddies had a run in with the DWP in about 2006. She had the Mobility Allowance because both of her legs were cut off just above the knee. A pretty valid reason or so you would think. Anyway, one of her sons asked her for a loan of £200 but she refused saying that she would buy what was needed but she wasn't going to hand over any cash 'cos she knew it would get spent on drugs. So he grassed her up to the DWP  saying that he regularly saw her dancing etc. Did the DWP  investigate? Not really. They instantly stopped this woman's Mobility Allowance and then told her to appeal. Six weeks later the appeal went through and all her benefits were paid to her and backdated to the date that the DWP stopped them.

Now, I'm all in favour of hammering benefit cheats but that woman's life was made hell and she had to borrow money from good friends to pay household bills during that time.
