Following Delhi chief minister Arvind Kejriwal's apology to former Punjab minister Bikram Singh Majithia, comedian-turned-politician Bhagwant Mann, president of the Aam Aadmi Party's Punjab unit has resigned from the party.

A day after Delhi chief minister Arvind Kejriwal apologised to former Punjab minister Bikram Singh Majithia, comedian-turned-politician Bhagwant Mann has resigned as president of the Aam Aadmi Party's (AAP) Punjab unit. Mann announced his decision on Friday and added that he will continue to fight against the drug mafia and corruption in Punjab as an "aam aadmi".

Mann had replaced another comedian-turned-politician Gurpreet Singh Waraich 'Ghuggi' as chief of the party's Punjab unit in May 2017.

A report on Hindustan Times said the decision to appoint Mann was taken following one-on-one meetings with MLAs, wherein Kejriwal had claimed a majority favoured of Mann.

"The majority of whom I spoke wanted (Bhagwant) Mann to lead the state," Kejriwal had announced, according to the report.

Mann's resignation comes a day after Delhi chief minister Arvind Kejriwal had issued a public apology to former Punjab minister and senior Akali Dal leader, Bikram Majithia, for levelling accusations against the latter over his alleged involvement in the drug trade.

Kejriwal had attacked the SAD-BJP government in the run-up to the Assembly elections in Punjab in 2017, in particular picking on Majithia and saying he was hand-in-glove with the drug mafia in the state, according to News18.

The AAP leader had also accused him of patronising drug trade in Punjab and called him a "drug lord".

In the letter, according to India Today, Kejriwal wrote, "In the recent past, I made certain statements and allegations against you regarding your alleged involvement in drug trade. These statements became a political issue. Now, I have learnt that allegations are unfounded. Hence, there should be no politics on such issues."

"I hereby withdraw all my statements and allegations made against you and apologise for the same," Kejriwal said.
