"PM Modi forgot he is India's prime minister and behaved like an opposition leader during the campaign," said Kumar Vishwas, a top leader of Arvind Kejriwal's Aam Aadmi Party (AAP), the morning after his party's spectacular victory in Delhi.
Mr Vishwas, a poet-turned-politician and a major crowd puller for the party, has in the past praised the Prime Minister on different occasions. He admits to having received an offer from the BJP to join them last year, an offer he declined.
Explaining why the party decided to invite the PM to Mr Kejriwal's swearing in on Saturday despite the acrimonious campaign, Kumar Vishwas called it "basic courtesy", one he says the Prime Minister failed to accord Arvind Kejriwal while campaigning.
But the AAP leader asserted that his party would not be defined by anti-Modi politics.
"Mamata's support for us does not mean that we will endorse the sort of politics that we are seeing in Bengal today."
BJP ally Uddhav Thackeray was among those who took the Delhi verdict to criticize PM Modi.
