Haryana’s Ambala Lok Sabha constituency is set to witness a contest between former two-term MP Kumari Selja of the Congress and the incumbent, Rattan Lal Kataria of the BJP, for the third time since 2004.Ambala, a Scheduled Caste reserved constituency, has traditionally seen a direct contest between the Congress and the BJP or its earlier avatar, the Jana Sangh, since 1967. Aman Kumar Nagra of the Bahujan Samaj Party in 1998 was the only non-Congress, non-BJP candidate to have won the seat.Currently a Rajya Sabha MP, Ms. Selja had defeated Mr. Kataria on both the earlier occasions in 2004 and 2009.

She also urged people to compare the development work carried out during her two previous stints as the Member of Parliament from Ambala. In 2014, Mr. Kataria had won the seat by defeating Raj Kumar Balmiki of the Congress after Ms. Selja opted to not contest the election.Development work The BJP MP, who had won the seat for the first time in 1999, is banking on the development work done by him in the constituency as well as the “good performance’’ of the NDA government at the Centre and BJP government in the State.Mr. Kataria, who on Friday filed his nomination, made it clear that he would focus on the achievements of the government headed by Prime Minister Narendra Modi, including the welfare work done for farmers and the poor. “Also, the BJP in Haryana has worked on the principle of ‘Sabka Sath, Sabka Vikas’. The State government has given a transparent and graft-free governance,” he told reporters.Besides the Congress and the BJP, Rampal Balmiki of the Indian National Lok Dal, who has been a member of Yamunanagar Municipal Corporation for four terms, and Naresh Saran of the BSP-Loktantra Suraksha Party alliance are also in fray .All 10 Lok Sabha constituencies in the State will vote in the sixth phase on May 12.
