Notes: 1. A single test sample may contain more than one class of drug; the sum of positive test results for class A, B and C drugs may therefore be greater than the overall number of positive results. 2. The percentages in the totals for class A, B and C drugs are the percentages of each class total against the sum of the class totals.

Armed Forces: Pay

Nick Harvey: To ask the Secretary of State for Defence how many personnel in the (a) RAF, (b) Army, (c) Navy, (d) Marines and (e) Reserves have been (i) overpaid and (ii) underpaid under the joint personnel administration system since March 2006. [158363]

Derek Twigg: The joint personnel administration (JPA) system was rolled out to the Royal Air Force (RAF) in March 2006, the Royal Navy (RN) in October 2006 and the Army in April 2007.

Information for the Royal Marines is contained in the RN information. The information on Reserves is not held centrally and could be provided only at disproportionate costs.

The RN and RAF figures for 2006 are as follows:

2006	RN Over	RN Under	RAF Over	RAF Under
March	0	0	0	0
April	0	0	4,064	1,804
May	0	0	230	475
June	0	0	257	288
July	0	0	139	120
August	0	0	2,979	7,058
September	0	0	4	0
October	0	0	0	0
November	9,618	2,289	1,200	1,678
December	0	0	0	0

From January 2007, JPA system errors are no longer recorded separately by service and figures are therefore not available for the Army. The combined figures for 2007 are as follows:

2007	Overpayments	Underpayments
January	161	1,383
February	70	0
March	229	54
April	13,908	252
May	3,430	1,181
June	0	90
July	2,978	416
August	0	51,917
September	0	12
