Comedian Ronnie Corbett, 81, collapsed at a south London restaurant while celebrating his CBE, his wife has revealed.

The former Two Ronnies star had been enjoying a Chinese meal with his wife the day after it was announced he is to be awarded a CBE in recognition of his services to entertainment and charity.

But he became ill and was taken to hospital by ambulance, later being transferred to a private hospital.

Corbett's wife said he had been feeling weak following a knee operation, for which he was receiving medication.

"They think it was a combination of this and the fact he had not felt like eating very much recently which led to the problem," she told the Croydon Advertiser.

"He has undergone a number of tests and all the results have come back clear, which is good news."

Corbett was allowed home last week.
