Tripura Pradesh Congress Committee President Birajit Sinha has called the Trinamool Congress a West Bengal based regional party and said regional parties have no impact on national-level politics.<br /><br /> “TMC is just a West Bengal based regional party. Regional parties have no impact on a national level. People don't like leaders who switch parties,” Sinha said on Congress leaders joining TMC. <br /><br />Sinha said TMC is “Bohiragata (Outsider)” in Tripura, something that the TMC used as a poll slogan against the BJP in the assembly elections of West Bengal.<br />
