Is my hon. Friend aware that Britain now has more than 3 million self-employed people, of whom 750,000 are women, many of them in south Derbyshire? Does he share their view that they work hard for their money, that they pay quite enough tax and national insurance and that they do not want to see what would be the worst disaster for such businesses in future—an increase in income tax and national insurance, as proposed by the Labour party?
