NEW DELHI: Delhi chief minister Arvind Kejriwal on Tuesday said he does not regret calling Prime Minister Narendra Modi a "coward and a psychopath " despite the statement turning into a massive row.

"I don't regret anything. I accept I use bad language, but I speak from the heart," the Aam Aadmi Party leader told NDTV. He had tweeted the remarks earlier this month after a controversial CBI raid on his office.

Kejriwal on Tuesday said his government has not done anything wrong in the Delhi and District Cricket Association ( DDCA ) scam and the CBI is free to conduct an inquiry against him.

"Kejriwal is not scared of CBI, order any inquiry against me," he said. Kejriwal alleged the CBI conducted raids at his office while turning a "blind eye" to the Vyapam scam of Madhya Pradesh.

On alleged irregularities in the DDCA, he said: "Whenever anyone takes the name of DDCA and corruption, (Finance Miniser) Arun Jaitley says he is being defamed." Jaitley, who was the president of the DDCA between 1999-2013, has filed defamation suits against Kejriwal and other AAP leaders over the row.

"When we (Kejriwal along with his deputy Manish Sisodia) met Prime Minister Narendra Modi, I told him I am like your child, please guide us, let us work without obstructions. He was silent," he added.
