BJP had alleged irregularities in the land deals involving Vadra and had raked up the issue during campaign in the 2014 Lok Sabha and before last month's Assembly polls to attack Congress.
Replying to questions, Khattar said that the BJP government will strive to give a clean and transparent administration to the people, besides curbing corruption with “an iron hand”.
BJP stormed to power in Haryana for the first time in the history of the state after the October 15 polls. After taking oath on October 26, Haryana Ministers Anil Vij and Capt Abhimanyu had said that the new regime will order a thorough probe into the alleged land scams and not spare anyone, even if it was Robert Vadra or former Chief Minister Bhupinder Singh Hooda.
