The ambulance service says that talks are under way

The BBC has seen outline plans to radically change the way some overnight calls are dealt with.

It shows stations at Saltash, Torpoint and Launceston could be affected.

On the Isles of Scilly, services provided by the boat ambulance could be cut if cash to plug a funding shortfall is not found.

Constant modernisation

Ian Hopkins from the union Unison says members are concerned about the possible effects on staff at the affected stations.

He said: "There's been constant modernisation in the ambulance service.

"Management have continually said that it wishes to match demand with the resources and we have no problems with that.

"We just want to make sure that's done in a sympathetic way to the staff. However, we have no detailed information about the proposals now."

The ambulance service said it would neither confirm nor deny the proposals shown to the BBC and would not comment on any of the specific points raised. It would only say that talks are under way.

The ambulance service bought the Isles of Scilly boat for the islands to cover emergencies.

But it is also used by GPs, health visitors, the police and fire brigade.

All user contribute to a charitable trust which covers the boat's running costs, but there is still a shortfall of �6,000.
