Cambridgeshire, Hertfordshire and Bedfordshire police HQs 'could merge'
Police control rooms in Cambridgeshire, Hertfordshire and Bedfordshire could be run by one force HQ to save millions of pounds, the BBC has learned.
It is understood the centre for the three could be based at Huntingdon, the headquarters of Cambridgeshire Police.
Another option being discussed by the counties' police and crime commissioners involves two bases.
Combining the three could save up to £7m. The plan was due to be made public in April.
Cambridgeshire PCC Sir Graham Bright said: "There is no decision at the moment, we are looking at every opportunity we can to save money and improve and increase efficiency."
Unison has been unavailable for comment.
Last month, Norfolk and Suffolk Police revealed talks to merge their force control rooms with the loss of at least 70 jobs, which would see all emergency calls answered at Norfolk's HQ in Wymondham.
Suffolk's Police and Crime Commissioner Tim Passmore said he needed to be convinced the proposals were "resilient and effective" and were in the best interests of people in Suffolk.
