PM backs National Insurance break

David Cameron has written to nearly two million businesses and charities to urge them to check whether they are entitled to a £2,000 National Insurance break which comes into effect this weekend.

The letters, on 10 Downing Street headed notepaper, are being paid for by the taxpayer rather than the Conservative Party, as they are being treated as part of the Government's efforts to publicise its policies and not as party political literature.
