Activist-politician Arvind Kejriwal is reportedly all set to for another 'expose' on Friday, the fourth by India Against Corruption. IAC members are tight-lipped about who the latest target will be.

In his last expose on October 31, Kejriwal led IAC accused the government of succumbing to corporates. Kejriwal and his colleague, lawyer Prashant Bhushan, termed RIL's D-6 block in the Krishna Godavari (KG) basin deal as a "classic case of crony capitalism" and said both the BJP-led National Democratic Alliance (NDA) and Congress-led UPA (United Progressive Alliance) governments were responsible.

In the past two months, Kejriwal has targetted Congress prsident Sonia Gandhi's son-in-law Robert Vadra's land deals, then law minister and now external affairs minister Salman Khurshid of allegedly misusing funds alloted to his NGO, and BJP president Nitin Gadkari's Purti group in an irrigation scam.

Meanwhile, former Army Chief V K Singh on Thursday said there was a need for thorough probe into the allegations made by IAC activist Arvind Kejriwal with regard to corruption.

"Kejriwal is levelling allegations of corruption because there are evidences to support them," Singh told reporters but refused to be part of IAC. "Loknayak Jayprakash Narayan had not joined any party ... He had moved ahead alone to fight corruption and people rallied behind him which resulted in a people's movement in 1974," he said in reply to a question whether he was interested in joining any political party.
