Of the 69 cities in the United Kingdom, the City of London is among the 30 that have lord mayors (or, in Scotland, lords provost). The Lord Mayor is entitled to the prefix The Right Honourable; the same privilege extends only to the lord mayors of York, Cardiff, Bristol and Belfast, and to the lords provost of Edinburgh and Glasgow. The style, however, is used when referring to the office as opposed to the holder thereof; thus, "The Rt Hon Lord Mayor of London" would be correct, while "The Rt Hon William Russell" would be incorrect. The latter prefix applies only to Privy Counsellors.
