asked Her Majesty's Government:

When HM Revenue and Customs approved mileage allowance payments were last revised; and when they will next be revised. [HL4717]

The approved mileage allowance payments system was introduced in April 2002 and the rate has remained unchanged since that date.

The Chancellor announced in Budget 2008 that the Government would maintain the current tax-free mileage allowance rates and thresholds. However, the Government keep all taxes under review.
