I found Cameron's Birmingham speech rather refreshing. He admits his party made mistakes, related to the economy, in government and opposition. And at long last he proposes a couple of concrete policies apart from the much repeated National Loan guarantee scheme.
-A 6 month VAT holiday (sounds expensive except that it's a "delay" in payments only)
-A one per cent cut in NI employers' contributions for the "smallest" firms
-A corporation tax cut by two pence for small companies
Also, he talks about more help for manufacturing, singling out the car industry as needing more help. Crikey. If that means much, which I doubt, that's quite a turnaround for the party which ended the government support culture for the car industry in the 1980s.
