Ambulance bosses were due to reveal their final plan for controversial changes to services across Oxfordshire.

Oxfordshire Ambulance Trust has already proposed closing eight bases across the county and replacing them with three modern depots, in Banbury, Oxford and Didcot.

The scheme has been criticised by leaders of health union Unison, who claimed patients could be put at risk during shift changes because ambulance crews would be unable to reach patients in remote areas quickly if they were all heading back to three destinations.

They also said members were not prepared to sit in their vehicles all day without access to lavatories, kitchens and relaxation areas. To address this concern, managers drew up plans for temporary stations across the county and started talks with the Local Education Authority about allowing paramedics to use school buildings.

In a statement, Oxfordshire Amublance Service said: "The OAS is committed to providing the best possible service to the people of Oxfordshire and to improving the working lives and conditions of our staff."

The final plans will be discussed by the new NHS watchdog, Oxfordshire County Council's health overview and scrutiny committee, later this month. It could refer the issue to the Government if it opposes the move.
