Leicester City Council has taken the final decision to adopt a directly elected mayor.
The Labour-controlled council has backed the decision despite opposition from other parties and criticism of the consultation process.
The decision marks the last stage of a three-stage process to change the governance of the city.
Elections for the new mayor will take place alongside full council elections on Thursday 5 May 2011.
An online consultation was held and of the 774 responses, 357 backed the mayor option, with 344 against and the rest giving no opinion or an alternative.
Any councillor who runs for mayor will have to resign from his or her seat if elected.
The mayor will be responsible for all decisions about council services for a four-year period and would personally select up to nine councillors as a supporting cabinet.
