Lieutenant Governor Najeeb Jung administered the oath of office and secrecy to Kejriwal, Manish Sisodia and five other ministers at the historic Ramlila Ground here, exactly an year after Kejriwal quit after a short 49-days regime.
Asim Ahmed Khan, Sandeep Kumar, Satyendar Jain, Gopal Rai and Jitender Singh Tomar also took oath of office and secrecy at the ceremony as a large crowd cheered.
Immediately, after taking oath, the 46-year-old leader addressed the gathering and unveiled the priorities of his government which included steps against corruption, communal elements, VIP culture and assured Delhiites that his government will fight for full statehood for the national capital.
Terming the verdict as 'miracle of God', Kejriwal said, "I knew people of Delhi love me, but didn't know they love me so much."
The AAP had won 67 of the 70 seats in Delhi decimating Congress and leaving only three seats for the BJP.
Assuring people that his government will make Delhi "India's first corruption-free state", he said if somebody asks for bribe don't refuse 'setting ker lena' (fix the deal) and video record it. Send the video footage to me. I will take action.
