Mr. Philip Hammond
To ask the Chancellor of the Exchequer how many letters have been sent in error by HM Revenue and Customs wrongly advising individuals that they have made insufficient national insurance contributions in respect of the financial year 2006-07.

Mr. Timms
The exercise to issue contributors with deficiency notices advising them of shortfalls in their national insurance contributions for the tax year 2006-07 started on the 31 August 2008 and ended on the 12 January 2009. A total of 2,862,065 letters were issued. No information is held on the number sent in error.
