Finance Minister Arun Jaitley Monday said Swiss authorities have not shared any information or given an assurance on sharing details about Indian account holders in Swiss banks, where a major portion of the black money is supposed to be stashed away."We have till now not received any information regarding the black money accounts from the Swiss authorities,” Jaitley told reporters. The finance minister was reacting to a media report that said Swiss authorities have agreed to share the details of Indian account holders. Jaitley said there is no official communication so far, and the Indian authorities will send a request to the Swiss authorities for sharing the information. "Our communication will be sent today itself,” Jaitley told reporters outside his North Block office.
