The battle for control of the Trinamool Congress (TMC) spilt further onto the legal turf on Sunday, with the Mamata Banerjee-led faction lodging fresh police complaints against dissident leader Ritabrata Banerjee and his associates, accusing them of illegally using the party’s name, symbol and organisational designations to mislead workers and supporters.

The complaints, filed by TMC’s joint national secretary Dola Sen, came a day after the party’s “Kalighat wing’’ had approached the Pragati Maidan and New Town police with similar allegations against the breakaway camp.
