The Driver and Vehicle Licensing Agency (DVLA) does not hold the information in the requested format.
However, a measure of process accuracy and loss is available from complaints statistics. In the financial year 2008 to 2009, DVLA issued 8.6 million driving licences. In the same period it received 1,584 driving licence related complaints (including medically related complaints). The Driver and Vehicle Agency does not hold a record of the numbers of driving licence applications lost before being processed at the Agency, nor those which are subsequently traced within the Agency.
