The Jharkhand Janadhikar Manch (JJM) with its MLA Bandhu Tirkey and the Rastriya Kalyan Pakshya (RKP) with its MLA Chamra Linda merged with the TMC in the presence of former Railway Minister and TMC General Secretary Mukul Roy.
"With the merger of two recognised political parties having their MLAs, the TMC now has presence in the Jharkhand Assembly," Roy told a press conference after the merger here.
Along with Congress and RJD, both the MLAs are currently supporting the ruling Hemant Soren government in the state.
Lalu Soren, younger brother of JMM chief Shibu Soren, has also joined the TMC, Roy said.
"With the joining of these leaders, TMC has become stronger. We have not yet decided how many seats to contest in the Lok Sabha, though we have kept the option open to contest all the 14 seats in Jharkhand," Roy said when asked whether Tirkey and Linda would contest Lok Sabha poll.
