Asked when he last used it, Mr Meddings said: “I had what turned out to be an unprovoked DVT late last year. I started within the health service. I went to my GP, and my GP referred me to scans in the health service. 

“I had a series of scans to find out what was the nature of the issue and then I did essentially then go… I was then referred privately.”

Ms Keeley then pressed: “Do you think you’re qualified then to inform the running of the NHS care, if when you have a health problem yourself you don’t trust the NHS?”

Mr Meddings said her claim was not “right”, and added “I absolutely trusted the NHS and I still do.”

After describing recent dealings with his GP, he added: “So actually, I am an absolute user of the health service. I’m passionate in believing in what it stands for and does.”

Health Secretary to have final say

Following the hearing, the committee will report on its views on the candidate’s suitability for the role which will be sent to Sajid Javid, the Health Secretary.

Mr Javid will then consider the report before making a final decision on the appointment.

The committee is unable to block the appointment if they do not believe he is suitable for the role.

If appointed, Mr Meddings will be paid £63,000 per year for working two to three days a week.

During the hearing, he also described the care the NHS provided to his late mother and younger sister who died after a long illness.

His twin has just retired as an NHS surgeon and his daughter is a fourth-year medical student.
