Lord Mayor of London
It was once use for Lord Mayors to be created knights when they took office and baronets when they retired. The custom was applied inconsistently from the sixteenth until the nineteenth centuries; creations became more regular from 1889 onwards. From 1964 onwards, the regular creation of hereditary dignities such as baronetcies stopped, but Lord Mayors continued to be granted knighthoods (usually of the rank of Knight Grand Cross of the Order of the British Empire) until 1993. Since 1993, Lord Mayors have not received any automatic honours upon appointment.
