The RSS on Thursday said the charges against Jay Shah, son of BJP President Amit Shah, can be probed if there is prima facie evidence but it is for those who allege a scam to prove it."Necessary enquiry should be done and action can be taken accordingly," senior RSS functionary Dattatreya Hosabale told reporters here, responding to queries related to the alleged spike in the turnover of a company owned by Jay Shah.He said there must be prima facie evidence for the charges to be enquired into. At the same time, he put the onus of proving the charges on those levelling them. "Those making the allegations should prove them first."The RSS leader also distanced itself from senior BJP leader Yashwant Sinha, who on Wednesday criticized the government for defending Jay Shah. Sinha had earlier created a furore after attacking the government's management of economy."They are in the BJP and they should discuss the issues within the party. We will not discuss it as it is not our obligation," Hosabale said, when a reporter asked about questions being raised vis-a-vis government by some BJP leaders including Sinha.He also downplayed a question by a journalist who said senior leader Murli Manohar Joshi had given in writing a complaint about the government and had met RSS chief Mohan Bhagwat in this connection. "He might have come here for some other reason," he said.
