The Swiss franc slipped against the euro and was near flat versus the dollar on Wednesday, giving back some of the previous session's hefty gains against both currencies after broadening concerns over debt hit risk appetite. The franc was down 0.1 percent against the euro compared to the New York close, trading at 1.2137 francs per euro at 0653 GMT. It was near flat against the greenback, trading at 0.8412 francs per dollar.
