GP Dr Katharina Frey, who runs a small practice in Cumbria, appeared on ITV's Daybreak this morning to discuss her concerns over plans to phase out the Minimum Practice Income Guarantee (MPIG).
"Our actual patient numbers are quite low, but we have quite high overheads, so we don't really have the economies of scale" she told the programme.
Dr Frey warned the "viability" of the practice might be threatened by funding cuts.
"We want to be able to provide excellent care, but if more and more funding is going to disappear, this will be getting increasingly difficult."
