Delhi's Chief Minister and Aam Aadmi Party (AAP) leader, Arvind Kejriwal, has been summoned by the Central Bureau of Investigation for questioning on Sunday as part of the agency's probe into alleged irregularities in the Capital's now-scrapped 2021-22 excise policy. Kejriwal has been summoned as a "witness" in the case, but his name has cropped up in court documents in relation to alleged meetings, fixing commissions for private players, and the entry of political players and businesspeople from the south into Delhi?s liquor business.
