Mayors are elected by their fellow councillors to serve in office for 12 months.
Photographs of the present and past Mayors of North Lincolnshire Council are displayed inside the council chamber.
Deputy Mayors are appointed at the same time as the Mayor is elected.
It is normal practice for the deputy to be nominated for Mayor the following year, although they still have to be elected by their fellow councillors.
The Mayoral robes are made from red wool trimmed with artificial fur. It has been suggested that the original fur on former Mayoral robes may once have been a 'flea trap'.
The Mayor's hat, called Bicorn, has gold braid, and the Deputy's has silver braid.
Lady Mayors wear a three-cornered hat called a Tricorn.
