- Arvind Kejriwal apologises for "making unverified allegations"
- Last week he had apologized to former Punjab minister Bikram Majithia
- AAP chief looking at closing all 33 defamation cases against him: Sources
In 2014, Mr Kejriwal had called Mr Gadkari "one of the country's most corrupt politicians" and had been promptly slapped with a defamation case.
In a note to the minister, Mr Kejriwal admitted to "making unverified allegations" and added, "I have nothing personal against you. I regret the same. Let us put the incident behind us and bring the court proceedings to a closure." After the apology, they both appealed jointly in court that the defamation case filed by Mr Gadkari be dropped.
A similar letter to Kapil Sibal and his son Amit Sibal refers to comments made by the Aam Aadmi Party (AAP) chief in 2013 and says "the allegations made against you and father were unfounded".
Sources say the Delhi chief minister intends to get rid of all 33 defamation cases against him through similar out-of-court settlements and one-on-one "understandings". The cases have been a drain on the party's money and resources, say AAP leaders.
Former Congress chief minister Sheila Dikshit and the BJP's Ramesh Bidhuri are next.
"I hereby withdraw all my statements and allegations made against you and apologise for the same," Mr Kejriwal wrote to him last week.
Upset by the capitulation, AAP lawmaker Bhagwant Mann quit as the party's Punjab unit chief and Aman Arora resigned as his deputy.
Perhaps the biggest challenge on Mr Kejriwal's "sorry" list is Finance Minister Arun Jaitley, who sued the AAP chief over allegations that he presided over corruption as chief of Delhi's cricket board DDCA. Mr Jaitley went personally to court to file the case, along with three union ministers as witnesses. He also asked for Rs 10 crore to compensate for what he called defamatory allegations.
