Martin Morgan (36) is the youngest of the SDLP councillors in Belfast. He was the youngest on the 51-seat council when first elected to his north Belfast ward in 1993.
This followed the departure of Dr Brian Feeney from both the SDLP and representative politics.
A childcare social worker in north and west Belfast, he is a former party vice-chairman of the SDLP and is deputy leader of the SDLP council group.
He is also the outgoing deputy chairman of the council's policy and resources committee.
An active trade unionist, Mr Morgan has been involved with policing and parades issues in north Belfast.
He says he would like to develop a common agenda for all the people of Belfast through consultation and co-operation between all parties, community groups and social partners.
He cites the example of his SDLP colleague, Mr Alban Maginness, the first nationalist lord mayor who was elected in 1997 with support from both Alliance and Sinn Féin votes.
Mr Morgan stood for the Assembly in north Belfast following the Belfast Agreement in 1998, but Mr Maginness took the SDLP seat in the constituency.
Mr Morgan's vote in city council elections has increased in the 10 years he has been in the City Hall.
He won just under 2,000 votes in the last local government elections in 2001.
Noted as a hard worker, Mr Morgan has made it clear that his political activity will be concentrated on Belfast.
He will not be a candidate in Assembly elections if suspension of the Belfast Agreement institutions is lifted.
His election means that, for the first time, Belfast City Council has had two consecutive nationalist mayors.
