Arvind Kejriwal's latest allegations today turned out to be on black money with the activist-turned-politician accusing prominent Indians, including the Ambanis, of having black money in Swiss bank accounts. Targeting the HSBC bank, Mr Kejriwal said it has indulged in money laundering and that the Ambani brothers, Naresh Goyal and Congress MP Annu Tandon are among those who had parked their black money in its Geneva branch.
