The Corinthia Hotel London, at the corner of Northumberland Avenue and Whitehall Place in London, is a luxury hotel and former British Government building, located on a triangular site between Trafalgar Square and the Thames.

Is it really former government bldg. or still used as staging/planning/meeting place for agencies and their agents? Why some Corithinthia chain Hotels were targeted by terrorist attacks in the past? Could this be the case of easier to control and stage FF in places familiar?
