Responding to questions from committee members at an open hearing on 10 November, Sir Bill Jeffrey, the permanent under-secretary for the MoD [Ministry of Defence], said the department may need to write off a large proportion of expenses errors worth GBP268 million (USD448 million) gross, identified by a National Audit Office (NAO) report published in July.

The NAO's review of the MoD's 2008-09 report of accounts found that 14.7 per cent of transactions carried out using the MoD's Joint Personnel Administration (JPA) expenses system were in error. (The JPA handles specialist pay, allowances and expenses for MoD personnel.)

When asked what proportion of the GBP268 million may eventually need to be written off, Terrence Jagger, the MoD's director of financial management, said: "At an educated guess – I'd say considerably less than half of it. GBP268 million is the NAO's estimate of gross error," he added. "Those errors arise from situations where we can't provide satisfactory evidence ... . It may well prove that GBP268 million is an over estimate."

For comparison, there are about 146,000 soldiers in the British Army and one civil servant for every two serving armed force members.in the MoD. My trusty calculator tells me that the average expense overclaim per civil servant was about about £2,680 each in one year alone, but it would be enough to give every British soldier going to Afghanistan a bonus of about £10,000 each (assuming they change shifts three times a year). Or indeed to pay compensation of £500,000 to every seriously injured soldier.
