"It was a legitimate political decision. The country at this time needs institutional reforms. We quit the national capital for larger institutional games," said Gandhi. (Agencies)
He also denied that the party would bear the brunt of Kejriwal's decision to resign as Delhi Chief Minister in just 49 days.
"Should the country wait for 5 more years for a Jan Lokpal? It was better we resigned from government and came back with a strong mandate and pass a strong anti-corruption law," he added.
The AAP leader has been fielded against sitting Congress MP Gurudas Kamat from North West Mumbai in the Lok Sabha polls.
He will also be facing Kamal Khan of the Samajwadi Party, Mahesh Manjrekar of the MNS and Gajanan Kirtikar of the Shiv Sena in the poll ring.
But he claimed to be in a favourable position over other contestants.
"From an internal survey that we have done, I am ahead of my competitors by at least 1, 00,000 votes. More than half of the people we spoke to, favoured the Aam Aadmi party over other candidates," he said.
The 55-year-old social activist also slammed the media
"Media has been the pillar of democracy. There has to be an objectivity in media reporting. That is missing," he felt.
To a query on who will AAP support to form the government after the Lok Sabha elections, Gandhi said, "Though a formal discussion has not taken place as yet, we may decide to support a party based on certain conditions like Jan Lokpal and corruption issues."
However, he was quick to add that this was his personal opinion.
"It was a legitimate political decision. The country at this time needs institutional reforms. We quit the national capital for larger institutional games," said Gandhi.
