The Left party will back the CPI candidate in Thowra constituency and the Congress nominees in Mariani, Bhabanipur, Tamulpur and Gossaiagon seats.
The bye-polls in Gossaigaon and Tamulpur have been necessitated due to the death of sitting MLAs, while the incumbent at Thowra resigned from his seat to join the ruling BJP.
Addressing a press conference here, Raijor Dal president Akhil Gogoi said his party's nominee Sanjib Gogoi will contest for the Mariani seat in the upcoming byelections.

He also appealed to the Congress, with whom RD had tried to project common candidates for the by-polls to defeat the ruling NDA, to support their nominees.
