Theresa May’s extra £20 billion NHS fund is not enough to keep the health service afloat long term, according to the National Audit Office (NAO).

The study said that staff shortages threaten May’s long-term plan which aims to reform the NHS by 2023.

The extra funding will broadly be distributed amongst GPs, community care, and mental health, but NAO warns it does not cover all key areas of health spending.

The fund will not cover the department of Health and Social Care which leaves training for doctors and nurses still searching for a budget boost.

Neurophysiologist doctor, Omar Al-Khayatt, said: “As a doctor on his way to being a consultant, you want to get good training.

“But service provision demands mean we are often stuck seeing the basic emergency stuff which might not necessarily help with training and often eats into training time.”

Dr Al-Khayatt also said that the long-term plan is actually short-sighted, and will lead to poorly trained doctors and trainee burnout.

NAO said this ‘presents a real risk’ that some of the extra funding will go on agency staff or will be unspent because of the lack of staff able to deliver the plan.
