12 of the 17 Congress MLAs in Meghalaya have joined the Trinamool Congress in a late-night coup on Wednesday.
The lawmakers include former Meghalaya Chief Minister Mukul Sangma.
The MLAs have already written to the assembly speaker Metbah Lyngdoh regarding this, NDTV reported.
This comes a month after Congress senior leader Rahul Gandhi met Sangma and the party’s state president Vincent H Pala over their demands.
The induction made Trinamool the principal opposition party in the state.
More details are awaited.
