East Brighton councillor Nancy Platts has thrown her hat in the ring for the upcoming Labour leadership contest in the city.
It comes after the current leader, Daniel Yates, announced he is to step down later this month.
He said: "Being leader has been the greatest privilege and biggest challenge but it’s left me exhausted for all sorts of reasons."
Labour won the most seats in the Brighton and Hove City Council elections last week, with 20 councillors elected.
It means the next Labour leader will also become the leader of the council.
Nancy Platts, who was reelected in East Brighton, said: "Following the announcement by Daniel Yates earlier today I wish to put myself forward as leader of the Labour Group.
"I would like to thank Daniel for all his hard work and service in contributing towards delivering Labour’s progressive policies during his time as both leader of the Labour Group and Brighton and Hove City Council.
"The voters of Brighton and Hove have demonstrated that they wish to see a progressive agenda adopted by the council and I believe my values, experience and leadership skills can play a major role in delivering this.
"I am proud of our manifesto and the change I believe it can deliver for our city. In the next few days I will be seeking the support of our Labour councillors for me to take forward our vision and values in the city."
Cllr Yates said he would serve as leader until May 22, until after the local party's annual general meeting when a new leader will be selected. He will continue to serve as a councillor in Moulsecoomb and Bevendean.
He also endorsed Cllr Platts as his possible successor and said: "It’s great news that Nancy Platts is putting her name forward. She has the integrity and determination to get the job done. I hope @BHGreens can open a sensible dialogue with her for the good of the city. @bhlabour would do well to support."
