Amid reports of minor skirmishes, 68.31 per cent voting was recorded in Haryana on October 21. The result will decide the fate of 1,169 candidates, including 105 women and a transgender.
Joint Chief Electoral Officer Inder Jeet told IANS that 91 counting centres have been set up at 59 places. He said each counting centre would be equipped with a three-tire security system.

However, all eyes are on Chief Minister Manohar Lal Khattar, Congress leaders Bhupinder Singh Hooda and Randeep Surjewala, Jannayak Janata Party (JJP) leader Dushyant Chautala and Indian National Lok Dal's (INLD) Abhay Chautala.

Riding high on pro-incumbency and the Modi wave, Khattar believes he will take his party's tally to '75 plus' from the present 47 legislators, while Hooda of the Congress has been raising the pitch against unemployment, law and order and lack of development.
The ruling Bharatiya Janata Party-Shiv Sena and the Opposition Congress-Nationalist Congress Party are the main parties in the fray, besides Raj Thackeray's Maharashtra Navnirman Sena, Prakash Ambedkar's Vanchit Bahujan Aghadi, the Owaisi's All India Majlis-e-Ittehadul Muslimeen and Arvind Kejriwal's Aam Aadmi Party.
