In more than 40 years as a broadcaster, right up to the last weeks before his death, Sir Clement established himself as one of Britain's most recognizable personalities. He cultivated a reputation as a grumpy, irritable but hugely entertaining performer. He won widespread public affection, particularly for his appearances since 1967 as a relentlessly inventive, assertive and witty panelist on the 30-minute radio show "Just a Minute," in which contestants vie to speak on offbeat topics for 60 seconds without "hesitation, repetition or deviation.".
