According to the excellent Mr John Tyers:-

“85,000 SEMMMS leaflets were sent out. The population of Stockport is 283,000. If you send questionnaires to the 30 per cent of the borough – such as Bramhall and Cheadle – where car ownership is very high, voters will tend to want their money spent on roads. If you go, however, to the poorer districts you would expect a very different result. Ten years ago 250,000 leaflets were distributed and three per cent of them were returned in favour of building the road. This time around we have no meaningful result. We have simply wasted public money.”
