New Delhi/IBNS: The municipal house of the national capital Delhi was adjourned for the third time in a month without electing the mayor over the row triggered by the 'change in rules' of the polls, media reports said.

The city's ruling Aam Aadmi Party (AAP), which has the majority, on Monday alleged the aldermen, who are allowed to vote, would favour the opposition Bharatiya Janata Party (BJP) in the elections to the posts of mayor and deputy mayor.

Aldermen are the nominated members of the civic body's house.

Municipal Corporation of Delhi or MCD's president officer Satya Sharma on Monday announced the aldermen would be allowed to vote leading to the uproar in the house.

The AAP, which is the rival of the country's ruling BJP, is set to move the Supreme Court challenging the decision to allow aldermen to vote.

AAP leader Atishi said as quoted by The Indian Express, "Last time we withdrew our petition against the BJP because by then the dates for mayor polls were approved and the voting rights of aldermen were also not clear whether the nominated members will vote or not but today it is clear, they have illegally given the Voting rights to aldermen.

"We will move to the Supreme Court and challenge the BJP’s decision."

The first couple of sessions, which were held on Jan 6 and 24 respectively, were also adjourned after ruckus and war of words between the members of the AAP and BJP.
