Plans were drawn up under Tony Blair for a major redevelopment of Downing Street costing hundreds of millions of pounds, including plans for an underground “safe-haven” to be used in the event of a terrorist attack, according newly-released official files.
The hugely ambitious programme – codenamed Project George – included plans for a two-storey “subterranean suite” under the No 10 garden, with a conference room capable of seating 200 people, which could also serve as a bunker in the event of a terrorist attack.
