The introduction and deployment of the UK's ID card scheme is likely to cost £400 million more than expected.
The bi-annual estimate of the public costs involved in the scheme came in at £5.31 billion, according to the government's Identity Cards Scheme Cost Report May 2007.
The new figure includes costs for staff required to deliver ID cards and future biometric passport production costs. Michael Parker, of anti-identity card group NO2ID, said costs were highly likely to continue going up. "Inevitably these numbers will rise further - there have been no allowances made here for integration, for example. Bear in mind the original plan was to roll cards out in 2008 - it's fair to say they're a bit behind."
