Thousands of members of the UK armed forces received incorrect salary payments because of a "catastrophic" computerised payroll system, an MPs' report says.
The Commons Defence Committee said in a report published today that it is difficult to exaggerate the magnitude of the failure of the JPA.
As a result of the failures, soldiers were short paid for months, while £28.9m was overpaid to others, the report said.
The JPA was implemented by IT supplier EDS, which has been linked to several problematic public sector IT projects, such as the Child Support Agency system.
EDS has paid more than £500,000 in compensation for the failure of the system, the MP report said.
The MOD has apologised for the problems, but insists that the £245m system is working better.
