The Bromhead Medical Charity was set up last year after the Bromhead Hospital in Lincoln was sold to private firm Nuffield hospitals.

Since then it has been buying treatment for patients on NHS waiting lists.

The charity says it has already spent about �300,000 on operations and has plans to spend much more in the next 10 years.

Patients have already been treated for hip and knee replacements, neurological conditions and cataract surgery.

Bromhead Medical is also committed to continue the service and will spend more than �2.5m to fast-track patients over the next decade.
