The NHS risks losing family doctors' goodwill, a Scottish GPs' leader has warned.

Dean Marshall, chairman of the British Medical Association's Scottish GPs committee, spoke out after a heated debate at last week's Scottish local medical committees conference in which family doctors discussed possible industrial action over alleged erosion of the GP contract.

Grampian GP John Reid told delegates that doctors could adopt measures that would not directly affect patients, such as prescribing expensive non-generic drugs and increasing referrals, but which would hit waiting times.

Although GPs rejected the call, Dr Marshall said the fact that it was mooted showed how angry GPs were. "I'm disappointed that we've got to the stage where doctors feel it's necessary to debate motions like this," he said.

"GPs are delivering high-quality services... but there is a real risk that the goodwill, upon which the NHS depends, is being lost."
