[Official Report, 8 January 2007, Vol. 455, c. 426W.]
Letter of correction from Jane Kennedy:
An error has been identified in the answer given to the hon. Member for Rayleigh (Mr. Francois) on 8 January 2007, Official Report, column 426W.
The correct answer should have been:
At April 2006 there were about 220,000 claims originally made by couples, who are recorded as having split up by that date, and for which there were outstanding undisputed overpayments over £10 for either 2003-04 or 2004-05.
