Conservative MP Ed Vaizey used a Westminster Hall debate on 20 January 2010 to criticise the amount of bureaucracy attached to the Criminal Records Bureau (CRB), which vets people working with children and vulnerable adults.
The Wantage MP said jobseekers in his constituency had faced long delays in their CRB checks being processed - jeopardising their chances of gaining employment.
Mr Vaizey also said the vetting and barring scheme had created a "climate of fear", and deterred people from getting involved in volunteering.
Home Office Minister Meg Hillier said in nearly 90 per cent of cases extended CRB checks were completed within 28 days.
Ms Hillier said charities including the NSPCC had reported no reduction in volunteering since the introduction of the checks, adding: "We are a nation of volunteers".
