AAP chief Arvind Kejriwal takes oath as Delhi Chief Minister at Ramlila Maidan

Seeking cooperation from the Centre to develop the national capital as world's best city and "forgiving" opponents for what they said during elections, Arvind Kejriwal on Sunday took oath as Delhi Chief Minister for the third time along with six Cabinet colleagues.

With thousands of tricolour and AAP flag-waving Delhiites in witness at the historic Ramlila Maidan where Kejriwal took oath twice earlier, Manish Sisodia, Satyender Jain, Gopal Rai, Imran Hussain, Kailash Gahlot and Rajendra Pal Gautam were also sworn in by Lieutenant Governor Anil Baijal at the ceremony that last for 40 minutes that ended with an address by the Chief Minister.

All took the oath in Hindi and in the name of God, except for Rai who took oath in the name of "martyrs of the Independence struggle" and Gautam who took oath in the name of 'Tathagata Buddha'.

There are no new faces or women in the Kejriwal team as he repeated all his previous ministers.

The ceremony was witnessed by specially invited 50 'Makers of Delhi', who included a bus marshal Arun Kumar who averted kidnapping of a six-year-old girl, a retired teacher who took up farming and a woman Delhi Metro driver among others.

This is the third time Kejriwal is being sworn in as the Chief Minister of Delhi, the first being in 2013 when led the government for 49 days before he resigned over the issue of Jan Lokpal Bill. In 2015, he won the elections again winning 67 out of 70 seats while this time, he won 62 seats.

Addressing the gathering after the official ceremony was over, Kejriwal said he wants to work hand-in-hand with the Centre for the development as well as the smooth functioning of the capital. He also sought Prime Minister Narendra Modi's blessings.

Emphasising that the bitter campaigning times are over, he said a lot of politics happened during the electioneering and he has forgiven his opponents for what they said.

"The elections are over. It does not matter who you voted for. Now, two crore Delhiites are part of my family. I will work for everyone. A lot of politics happened during campaigning. Some parties said something. Whatever our opponents said about us, I have forgiven them," he said.

Noting that AAP's victory is not his but that of every mother, sister, youth and students, he said "this is the victory of every family."

Inviting all parties to be part of the development story of the capital, he said, "I will work with the Centre to develop Delhi. We will work hand-in-hand. I had invited Prime Minister Narendra Modi for the swearing-in ceremony but he has some other programmes...I seek his (Modi's) blessings for the smooth governance of the capital."

Concluding his speech by singing the Hindi version of "we shall overcome", Kejriwal said he did not discriminate anyone because they did not vote for AAP and would work for everyone.
