A Lord Provost is convenor of the local authority, the civic head and the lord-lieutenant of one of the principal cities of Scotland. The role is similar to that of a mayor. Only the cities of Aberdeen, Dundee, Edinburgh and Glasgow have a Lord Provost; other Scottish local authorities have provosts or convenors.
A Lord Provost has a higher status than a Lord Mayor in other parts of the United Kingdom. He is ex officio the lord-lieutenant for that city, in accordance with section 1 of the Lieutenancies Act 1997, which allows the city council to choose its own representative for the monarch.
The Lord Provosts of Edinburgh and Glasgow enjoy the style of " The Right Honourable" before their office, but not their names.
Permission to use the title is granted to a city by the monarch, under the royal prerogative, acting on the advice of government ministers.
