"Law will take its own course," he said when asked by reporters here to comment on the land deals involving the son-in-law of Congress President Sonia Gandhi.
Asked about other alleged land scams during the previous Congress government in the state, Khattar maintained that the law will take its own course. Khattar was speaking to reporters after his Minister, Bikram Singh Yadav, assumed charge at the Haryana Civil Secretariat here.
When asked to comment on Vadra reportedly losing his cool and pushing the microphone of a reporter in Delhi when questioned about land deals involving his company, Haryana's Health Minister Anil Vij told reporters in Ambala on Sunday that "one only reacts in such a manner and shows anger when one has something to hide".
Vij said that the media was just doing its job as it is its responsibility to ask questions and dig out facts. He said the way Vadra reportedly behaved showed that he has "little respect for the media".
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.
