The Opposition candidate, Winnerson D. Sangma of the Congress, was also accompanied by a host of Congress legislators when he filed his nominations.
The election was necessitated following the demise of Assembly Speaker, Donkupar Roy on July 28. Roy, who was the President of the UDP, was elected to the post of Speaker on March 12, 2018.
The election of new Speaker will be held on September 13, the last day of the Assembly's autumn session.
"With the support of colleagues in the MDA, there's no doubt why I should not win the Speaker's election," Lyngdoh said.

Going by the numbers,Lyngdoh is expected to comfortable defeat Sangma as the MDA government has a total of 40 MLAs.
However, Leader of Opposition, Mukul Sangma voiced confidence that the opposition candidate may win the election.
"Though the Congress has only 19 MLAs, but the Opposition has put up the candidate to win the election. Politics is like a game of chess," he said.
