The AAP on Thursday said BJP did not allow the MCD to function for two-and-a-half months, but councillors of Delhi Chief Minister Arvind Kejriwal "snatched the mayor's post from the BJP's mouth".The Aam Aadmi Party (AAP) organised an event at the party headquarters here to celebrate its victory on the mayor and deputy mayor posts. Delhi Chief Minister and AAP national convenor Arvind Kejriwal were to attend the event, "however the Central government put up barricades on the way to the AAP office and BJP leaders attacked the vehicles of AAP councillors and newly elected Mayor Dr Shelly Oberoi", alleged the party.
