New Delhi: Aam Aadmi Party national convener Arvind Kejriwal will be taking oath as the Chief Minister of the National Capital Territory of Delhi for the third straight time on Sunday at 12:15 in the noon at the historic Ramlila Maidan in an "open to public" event.

Those who contributed to the development of the city will share the stage with Kejriwal

Marking a shift from the traditional gathering of political heavyweights on the swearing-in ceremonies, Kejriwal’s oath taking event is expecting a ground swarmed by the residents of Delhi.

Prime Minister Narendra Modi has been invited to the ceremony, besides BJP MPs and MLAs from Delhi. The AAP had said no chief minister or political leader from other states will be part of the event as it will be a "Delhi-specific" ceremony.

Around 50 people from different walks of life who are 'Delhi ke Nirmata' and contributed to the development of the city during the last five years will share the stage with Kejriwal during his ceremony as special guests, AAP leader Manish Sisodia said.

Those invited include international tennis player Sumit Nagal, Delhi government school student and beneficiary of Jai Bhim Mukhyamantri Pratibha Vikas Yojana who cracked IIT Vijay Kumar, mohalla clinic doctor Alka, bike ambulance service officer Yudhishtir Rathee, night shelter caretaker Shabina Naaz, bus marshall Arun Kumar, Signature bridge architect Ratan Jamshed Batliboi and metro pilot Nidhi Gupta.

"Baby Mufflerman'' Aavyan Tomar, who stole the hearts when he dressed up as the AAP convenor on counting day, is a 'special invitee' at the ceremony.

Kejriwal calls dinner meet at his residence: 

On the eve of swearing-in ceremony, Kejriwal called a dinner meeting of his ministers-designate to discuss the roadmap for Delhi's development, especially the initiatives that need to be prioritised in the coming three months, according to party functionaries.

All the six ministers in the previous government -- Manish Sisodia, Satyendar Jain, Gopal Rai, Kailash Gehlot, Imran Hussain and Rajendra Gautam -- have been retained.

Ramlila Ground preparations: 

Workers were on Saturday giving a fresh paint job to the white ceremonial platform at the Ramlila Maidan, and the area around it was being decked up with potted plants and flowers.

From sprucing up the sprawling ground to extensive traffic and security arrangements, workers and authorities were busy making final preparations on Saturday.

Security: 

A large contingent of security personnel was given briefing by Delhi Police authorities at the Maidan.

Officials said 2,000 to 3,000 security personnel from the Delhi Police and paramilitary forces, including the CRPF, were being deployed for the ceremony which is scheduled to begin at 10 am. Drones were likely to be used for aerial surveillance.

Traffic regulations will be in place in the area from 8 am to 2 pm, they said.

In a near-repeat performance of 2015, the Kejriwal-led Aam Aadmi Party, which was floated in November 2012, retained power with a scintillating win in the just-concluded Delhi Assembly polls, trouncing its main rival BJP and completely decimating the Congress in a keenly-watched battle that took place in the midst of anti-CAA protests.
