"I want to assure the public that we will carry out development in the state (Haryana) as per Prime Minister Narendra Modi's vision. There will be no partiality on development front, which the state has experienced.
"There will be all-round development of Haryana... be it south or north Haryana," Khattar said, after being elected as Leader of BJP Legislature Party which paved way for his becoming the first Chief Minister of saffron party in Haryana.
"We will ensure good and corruption free governance in the state," he said, while expressing gratitude to Haryana voters for giving mandate to BJP for forming the government in the state.
He further said he would stress on uplift of those areas of the state which have been left backward. Khattar said the BJP had a team of experienced leaders who are capable of taking the state to newer heights as far as development was concerned.
