Edward Leigh, MP for Gainsborough, and chairman of the influential Public Accounts Committee, insists HERE that unless the Tories pledge reductions in taxes, they have no hope of being elected.
He claims the majority of the Tory MPs want David Cameron to set out an agenda for cutting taxes immediately.
He said shadow chancellor George Osborne was wrong to say tax cuts could destabilise the economy.
Mr Leigh told the Press Association:
"You can't win the next election by being all spin.
You will be torn apart by Gordon Brown, who will say you are all spin."
Mr Leigh was speaking at the launch of a leaflet by the Thatcherite No Turning Back group of MPs, which was fronted by right-winger John Redwood and titled "The Case For Lower Taxes".
The difficulty for David Cameron is that a few months ago he appointed John Redwood to head up his Economic Competitiveness Policy group.
