200 extra staff are moving to the Ministry of Defence headquarters at Abbey Wood near Bristol.

The body parts and tissue of soldiers killed in Afghanistan have been kept by the Ministry of Defence without the permission of their families.
Officials have admitted that six body parts and more than 50 tissue samples were retained by the Royal Military Police.
They were discovered last month when a new manager was appointed at the Military Police's Special Investigations Branch (SIB).
An urgent investigation has been launched and the MOD are trying to identify and inform the families affected.
