Cllr Price, who represents the Gorslas ward for Plaid Cymru, had led the authority since 2022, when he succeeded Emlyn Dole after Plaid retained control of the council. He will continue to serve as a councillor but will no longer hold the leadership role.
In a statement issued on Wednesday, the council said Deputy Leader Councillor Linda Evans will carry out the functions of the Leader until a new appointment is made. Councillors are expected to formally choose a new Leader at the full council meeting on 10 December 2025.
During his time in office, Cllr Price highlighted priorities including tackling climate change, supporting residents through the cost‑of‑living crisis, regenerating the local economy, improving housing and education, and strengthening public transport and council services.
His sudden resignation comes as Carmarthenshire continues to manage major regeneration projects and community services.
