Dr John Cormack has been protesting for years against severe underfunding at his surgery.
He claims he is not paid a penny and even donated nearly £5,000 to pay staff wages.
Now Dr Cormack, who serves 4,000 patients at the Greenwood Surgery in South Woodham Ferrers, has taken his campaign one step further.
No longer known as Dr John Francis Cormack, he is now Dr John Cormack - the Family Doctor who works for the NHS for free.
