§ Mr. Gibb
To ask the Secretary of State for Work and Pensions how many cases were the subject of rolling reviews in each of the last five years in determining the level of fraud in jobseeker's allowance and income support. 
§ Malcolm Wicks
The total number of sample cases has been around 30,000 since the start of the area benefit review programme. The number for each reporting period is in the table.
The smaller sample size for 2001–02 was introduced as part of the move to a common sample for determining levels of fraud and customer error, and official error. The smaller sample size for 2002–03 is a result of the Department restructuring from 13 areas to 11 Government office regions. Neither of these reductions in sample size will result in a reduction in the confidence levels of the reported results.
