Sultan Mohammad Mansur, the lawmaker-elect from Gonoforum banner, has taken his oath as a member of the parliament.
Speaker Dr Shirin Sharmin Chaudhury administered him oath at Jatiya Sangsad this morning.
Former Awami League leader and ex-vice president of Ducsu Sultan Mansur was elected MP from Moulvibazar-2 constituency.
He has gone outside the decision of his party Gonoforum and its greater political alliance Jatiya Oikyafront to take oath as lawmaker.
The other lawmaker-elect of his party Mokabbir Khan did not take oath.
DEBATE OVER THEIR JOINING THE JS
Senior Gonoforum leaders said they would take all kinds of actions against the two leaders if they took oath disobeying the party's decision.
Just around a month before the national election, the BNP, the Gonoforum and some other political parties had formed Jatiya Oikyafront.
Oikyafront leaders, including Dr Kamal Hossain, boycotted the polls results and called for a new election.
The BNP won only six seats against 289 by the ruling Awami League-led Grand Alliance.
All the six MPs-elect of BNP decided not to join the Jatiya Sangsad.
Talking to this newspaper, Sultan Monsur earlier said Dr Kamal knew about their oath.
