Before the swearing-in ceremoney, Maurya has said that he has no issues with Adityanath being chosen as CM.
"No issues with Adityanath being chosen as CM. I have been entrusted with responsibility of Dy CM; will work on law & order situation", said KP Maurya, reported news agency ANI.
Meanwhile, BJP's female firebrand leader Uma Bharti also expressed happiness for her "younger brother".
"For me Modi ji being the PM of India, & my younger brother Yogi ji becoming UP CM is the best news of the 21st century", said the union minister.
The Uttar Pradesh Chief Minister-elect Yogi Adityanath on Saturday said that he would follow Prime Minister Narendra Modi's 'sabka saath, sabka vikas' slogan and exuded confidence that the state would march on the path of development.
"I am thankful to Governor Ram Naik who invited me to form government in UP," he said in his first brief media interaction at Raj Bhawan.
Adityanath said he would follow Prime Minister Narendra Modi's slogan "sab ka saath, sab ka vikas" (With all and development of all) and ensure all round development of the state.
"I am confident that the state will march on the path of development," he said.
The Yogi said his efforts would be to provide "good governance" in the state. He thanked party MLAs for reposing faith in him.
The 44-year-old five-term MP from Gorakhpur was earlier in the day elected the BJP legislature party leader at a meeting of the newly elected MLAs, a week after BJP won a resounding three-fourth majority in the key Hindi heartland state, making a comeback to power after 14 years.
