Meanwhile the decision to end duty-free sales for travellers within the European Union was made unanimously by the economic and finance ministers (Ecofin Council) of the member state governments in 1991. That decision, which will take effect next summer, has been reaffirmed by the Council in recent years. The Commission is, naturally, obliged to implement that law. It will affect all travellers including, of course, diplomats and Commissioners.
There is no connection between 1961 arrangements and the 1991 decision.
Member of the European Commission
