New Delhi: Aam Aadmi Party MP Sanjay Singh on Saturday said he would contest the defamation case filed by former Punjab minister Bikram Singh Majithia against him even as the party chief and Delhi chief minister Arvind Kejriwal has apologised for alleging that the Akali Dal leader was involved in the drug trade.

Refusing to comment on the apology tendered by Mr Kejriwal, Sanjay Singh said: “I stand by whatever I have said in the past and irrespective of whatever is being said here and there. I will not retract from my stated stand.”

The AAP MP refused to be drawn into the controversy that has caused a virtual rebellion in the Punjab unit of the party after state chief Bhagwant Mann and another leader resigned from their posts. “I will not comment on this. I have stated my position as an individual,” Mr Sanjay Singh told a news agency.
