Chandigarh, Oct 22 (Inditop.com) Indian National Lok Dal (INLD) president and former Haryana chief minister Om Prakash Chautala Thursday pulled off a tough win Thursday when he defeated state Finance Minister Birender Singh in the Uchana Kalan assembly seat.

Chautala defeated Singh by a margin of just 621 votes on this seat in what is perhaps the biggest contest among all 90 assembly seats in the state.

Birender Singh, a powerful Jat community leader from Jind district, was aspiring to be chief minister if the Congress returned to power.

Chautala, who contested two assembly seats, was leading from the Ellenabad seat in Sirsa district by over 16,000 votes and was expected to win that comfortably as well.
