Doctor Amir Khan was all smiles when he won Celebrity Mastermind for charity last night.

Dr Khan and three other well-known names - Gogglebox star Mica Ven, BBC newsreader Jane Hill and comedian Jamie MacDonald - were invited to sit in the famous black chair for what is dubbed "Britain's toughest quiz".

The BBC One show, hosted by Clive Myrie, sees people being asked questions about their specialist subject followed by a general knowledge test.

Dr Khan's specialist subject was American R&B band TLC - he got six questions correct.

In his general knowledge round, he answered seven questions right - meaning he earned a total of 13 points during the programme.

Mica and Jane also ended up with 13 points - but because Dr Khan did not pass on any of his questions, he won the coveted Celebrity Mastermind trophy.

Dr Khan quipped: "Celebrity Mastermind trophy - just what the doctor ordered."

By taking part and winning, a donation has also been made to his chosen charity, Sue Ryder Manorlands Hospice in Keighley.

'I don't sleep very much'

Dr Khan works as a GP at the Ridge Medical Centre in Great Horton and is also well-known for his regular appearances on TV.

During the quiz, host Clive said to him: "You are a Renaissance man - regular on (ITV show) Lorraine, best-selling author, GP of course. How do you fit it all in?"

Dr Khan laughed and answered: "I don't sleep very much."

Clive then asked: "What's the reaction of your patients to you being this famous TV doctor? Are they all queuing up to try and see you and you alone?"

Dr Khan responded: "No! I've been working at the same practice in Bradford for 12 years so they've known me longer than I've been a TV doctor, so it's just normal for them to come and see me."

He added that he has two sisters who are doctors - one works as an A&E consultant while the other is a surgeon.

Mastermind started in 1972 and has had four previous presenters – Magnus Magnusson, Peter Snow, Clive Anderson and John Humphrys.

It was the brainchild of TV producer Bill Wright, a former RAF gunner, who drew on his wartime experience as a prisoner of war in Germany of answering three questions - name, rank and number - to create the Mastermind ritual of contestants being asked their name, occupation and specialist subject.
