Unruly scenes marred the election of the North Delhi mayor Preeti Aggarwal and deputy mayor Vijay Kumar Bhagat in the headquarters of the meeting hall of the Civic Centre on Thursday.

Slogans of Bharat Mata ki Jai, Har Har Modi, and Jai Shri Ram reverberated in the hall. Congress and AAP councillors took strong exception to this, calling it a "violation of protocol."

Opposition members also raised objections on the entry of BJP supporters and 'unauthorised' members in the meeting hall.

"How can the authorities allow hoards of supporters up on the stage chanting slogans even as the session was going on? This is a complete violation of the decorum of the House," said Leader of Opposition Rakesh Kumar from AAP. Kumar, along with Congress councillors, called it a "failure" of the authorities and alleged that there was gross "mismanagement" on their part.

The protest comes in the aftermath in the BJP's sweeping victory in the recently held civic polls. The BJP had won 181 of the 270 municipal wards with AAP and the Congress trailing behind at 48 and 30 seats, respectively.

Speaking after the election, Preeti Aggarwal, 43, who is the BJP councillor from Rohini, said that her focus will be on the 3S —Swachhta, Swastha and Shiksha.

"My priority as the mayor will be to take everyone along to work on making PM Modi's Swachh Bharat a reality. We need to develop Delhi on the lines of Smart City," said Aggarwal.

However, the Congress councillor from Malka Ganj, Guddi Devi, who played a part in the disruption of proceedings alleged that the new mayor, "is not aware of the rules of the House."

Devi also alleged that no room was allotted in the headquarters for Congress councillors.
