- Arvind Kejriwal said even the opposition does not believe Kapil Mishra

"I would have been in jail had there been an iota of truth in his allegations," the AAP chief said at a party meeting.
"They ask me why am I silent? Why I am not responding? How does one respond to these allegations! No one believes them - even the opposition doesn't believe the charges," Mr Kejriwal added.
"When your own betray you, it hurts a lot," he further said.
Kapil Mishra was sacked as a minister in the Delhi government by Chief Minister Arvind Kejriwal earlier this month. The AAP had then said that the decision was taken due to Mr Mishra's "poor performance".
On Sunday, the suspended AAP member claimed that a person who was under investigation over a Rs 400-crore scam had funded the foreign tours of senior AAP leaders Sanjay Singh and Ashutosh.
Mr Mishra had also undertaken a hunger strike last week to protest against the top AAP leadership but he quit the fast yesterday after falling ill during a press briefing.
