Swiss and U.S. officials have met in recent days in Berne to try to end a long-running dispute over wealthy Americans using secret Swiss accounts to dodge taxes, and seem to be getting closer to a deal, two newspapers reported on Sunday. The fact that Michael Danilack of the U.S. Internal Revenue Service travelled to Berne for the first time to meet Swiss negotiator Michael Ambuehl was seen as a positive sign. "That shows the U.S. has a considerable interest in the negotiations and that a breakthrough seems possible," an unnamed Swiss diplomat told the NZZ am Sonntag newspaper. Mario Tuor, a spokesman for the Swiss secretariat for international financial affairs, confirmed the talks had taken place, but declined to comment further beyond saying more negotiations were planned.
