MUMBAI: NR Narayana Murthy , the founder of Infosys Technologies , has revealed that he had spurned a request last month from Arvind Kejriwal , the activist-turned-politician, to fund his political activities."Mr Kejriwal approached me in September 2012 asking for financial assistance, I declined. I have not financially supported Mr Kejriwal's political activities," Murthy said.Kejriwal has shaken the country's political establishment with a series of so-called exposes. His targets, which have included Robert Vadra - the son-in-law of Congress President Sonia Gandhi BJP President Nitin Gadkari and External Affairs Minister Salman Khurshid , have set off media firestorms.Murthy detailed his relationship with Kejriwal since 2008 in a statement released on Tuesday.The Infosys founder and chairman emeritus issued the statement after a news report in Mail Today named the Tata Group and Murthy as the two leading donors to Public Cause Research Foundation, Kejriwal's flagship NGO.The Tatas also explained their role in a statement issued on Monday. "The Tata Social Welfare Trust , or TSWT, clarifies that it did not donate any money to Public Cause Research Foundation, Ghaziabad, of Arvind Kejriwal for any political activities, contrary to reports in a section of the media," a statement from the Tata Group said.In his statement, the Infosys founder said his relationship with Kejriwal dates back to 2008 after the activist approached him seeking financial help to raise awareness about the Right to Information ( RTI ) Act. The Infosys chairman also roped in the Tata Group."Mr Arvind Kejriwal approached me in 2008 to donate money to raise awareness about the RTI Act by instituting awards to recognise the contribution of public information officers, public information commissioners, NGOs and citizens. I agreed to give Rs 25 lakh a year for five years and requested Tatas to contribute an equal sum, which Tata Social Welfare Trust was kind enough to agree," the statement said.In all, the Infosys founder contributed over Rs 1 crore between 2008 and 2011 which was used to recognise the work of information officers and to help some of the families of RTI activists who had been murdered.Some of the money was used to fund the "secretarial expenses" of the Jan Lokpal bill , a legislation proposed by the anti-corruption group led by Anna Hazare, the former leader of the anti-corruption movement who has now stepped aside in favour of Kejriwal.The statement by the Infosys founder explains the circumstances under which his contribution, meant to fund the RTI movement, ended up getting used in the Jan Lokpal movement.In 2011, Hazare went on fast on two occasions, in April and August, to force the Congress-led UPA government to accede to his version of the Lokpal legislation. Though he eventually did not have his way - the Lokpal bill remains in limbo - the movement rocked the government and eroded its authority.
