"The President is pleased to appoint Shri Harishankar Brahma as the Election Commissioner in the Election Commission of India with effect from the date he assumes the Office," said a notification issued by the Law Ministry.
Brahma was appointed Election Commissioner following the elevation of S Y Quraishi as the Commission's head.
It is understood that Prime Minister Manmohan Singh was keen to appoint an officer from the North East to the key post.
Brahma is the second person from the North East after J M Lyngdoh, who retired as Chief Election Commissioner in 2004, to become Election Commissioner.
