GPs in Wales say they're concerned about their ability to provide quality care for patients as they claim they face a £25m "black hole" in funding.
They warn of longer waiting times for GP appointments, a cut in services and greater workloads for doctors if more cash is not made available.
The Royal College of General Practitioners say latest figures reveal that the amount spent in general practice per person has dropped by 7.6% in real terms between 2008 and 2012, due to a combination of funding cuts and population growth.
For the fourth year running, GP surgeries in Wales have suffered a decrease in resources, with real terms investment in general practice falling to £469m in 2012/13 from £495m in 2008/09 they say.
Paul Myres, Chair of the RCGP in Wales said, “Many are practising from inadequate premises and are increasingly unable to meet the needs of patients. The Welsh Government has recognised that there are areas of Wales where health care is not meeting the additional needs of deprived communities."
Nearly half of GPs had already had to cut back on the range of services they provide for their patients and over 70% predicted longer waiting times for GP appointments within the next two years says the college.
