Apparently, if I buy a house in the Northamptonshire town of Corby, it’ll be free and they’ll give me spending money on top! House prices 154% lower than London eh?

(The site has now been corrected. But the poster campaign – which I noticed in all its erroneous glory this morning at Baker St Tube – remains in force.)

This sort of thing really bugs me, because ads from public bodies pass under so many pairs of eyes before approval that someone should possess the equivalent of GCSE Maths. Unfortunately, nobody does. Remind me never to visit Corby.
