Trinamool Congress chief Mamata Banerjee has called for unity in the party as it witnesses a mass exodus of councillors following the party's defeat in the West Bengal assembly elections.
Over 100 councillors have resigned or stopped attending offices, with several municipalities witnessing group resignations.
TMC sources said Mamata told party workers to stand together in difficult times, adding that those unwilling to continue with the organisation were free to take their own decisions.
State minister Agnimitra Paul criticised the TMC, alleging that the absence of elected councillors is disrupting basic civic services and affecting day-to-day administration.
Mass resignations have been reported in North 24 Paraganas, Bhatpara, Kanchrapara Municipality, Garulia Municipality, North Barrackpore Municipality, Contai Municipality, and Diamond Harbour.
