Police chiefs could be forced to rent extra offices because the new Scotland Yard is too small. The embarrassing disclosure comes just days after the current Metropolitan Police Service HQ was sold to an arab investment group for £370m.
An internal report for MOPAC, the Mayor's Office for Policing and Crime, admits additional money may have to be spent to accommodate some police activities.
The new police hq, also to be called New Scotland Yard, is a refurbished office block on Victoria Embankment, known as Curtis Green.
It is too small for the Met's legal team which will now move to Holborn police station.
The bill for converting Curtis Green already stands at £58m.
The move from the current Scotland Yard in Victoria was supposed to save £6m a year in running costs.
