Many of the London-based officers from the Royal Parks Constabulary transferred into the new Metropolitan Police Royal Parks Operational Command Unit (OCU) — the new OCU is funded in the same way, through the Royal Parks Agency, with its funding "ring-fenced" to prevent it being diverted to other Metropolitan Police areas and many others transferred into British Transport Police, as within London, Royal Parks Constabulary paid to share a control room (and subsequent radio channels), crime recording systems and human resources functions with BTP.
