Spy buildings broke budget.
Government accounting procedures were breached when new premises were bought for MI5 and a new building was constructed for MI6, according to a recently declassified report. The reports reveal that costs spiralled out of control and that Margaret Thatcher, prime minister at the time, was not kept informed of the rising expenditure. The final cost for Vauxhall Cross, the MI6 building, and MI5’s Thames House, rose to £548m, up from estimates that originally totalled £250m. The newly released reports were produced in 1993 and 1995 and include a report from the then chairman of the Public Accounts Committee Robert Sheldon.
