David Duke-Cohan was admitted to the profession in October 1952, the month that Britain tested its first atomic bomb, the newly formed nation of Pakistan played its first cricket Test match and Birds Eye sold its first frozen peas.

Duke-Cohan, now 84, is still practising – as a consultant at London firm Myers, Fletcher & Gordon – and in the intervening 60 years has represented clients ranging from the famous and infamous, to major corporations and the man in the street.

He said: ‘One day I will retire, but for now my clients won’t let me. I have thoroughly enjoyed my 60 years in the profession. Understanding the needs of your client is the key to success. Being able to provide advice with a smile also helps.’
