A by-election to fill a vacant seat held by a former Labour councillor in Darlington will be held in December.
Darlington Borough Council confirmed that a vote will take place in the Red Hall and Lingfield ward on Thursday, December 11.
Former councillor Amanda Riley stood down from the role in October due to ill-health. She had been a councillor since 2023 and was previously a cabinet member for stronger communities.
The by-election will be the first council vote since an all-out election in May 2023.
Darlington Labour will be fighting to defend the seat, which it gained overall control of in 2023. Councillor Mandy Porter also represents the ward for Labour.
Praising her colleague's community work, Cllr Porter said: "I would like to thank Amanda for all her hard work in serving the residents of Red Hall and Lingfield and supporting me across the ward.
"I know this has been a very difficult and sad decision for Amanda to make, but she is stepping down as a result of ill-health."
A full list of candidates will be released following the nomination deadline on Friday, November 14.
The current makeup of the council consists of 23 Labour, 13 Conservatives, six Greens, five Independents, and two Liberal Democrats, with one vacancy.
Completed nomination forms must be delivered by hand to the council's returning officer at Town Hall, Feethams, Darlington, DL1 5QT, no later than 4pm on November 14.
