Sources said that the delegation, which will lay special focus on a number of pending requests, will be led by Revenue Secretary Shaktikanta Das and will have CBDT Chairman KV Chowdary and two other officials of the finance ministry's foreign taxation wing as its members.
The official visit, sources said, was set up in quick time after the Supreme Court-appointed Special Investigation Team (SIT) was taken into confidence by investigative agencies that a one-on-one visit between the officials of the two countries was necessary to take the probe in these cases forward.
Officials said that the decision to send the team has also been cleared by Finance Minister Arun Jaitley and the officials would be armed with legal documents, dossiers and the charter of the SIT to satisfy the Swiss authorities as to how much "importance India is giving to unravelling the facts in these cases keeping in mind public sentiments and the government's commitment to unearthing black money".
The upcoming meeting will be the first high-level one between the officials of the two countries after the Narendra Modi government came to power at the Centre with a poll-time promise that it would probe all cases of illegal funds stashed away abroad and ensure legal action in them.
