Danish European Constitution referendum

The Danish referendum on the Treaty establishing a Constitution for Europe was a planned referendum to be held on 27 September 2005, that would have put the proposed Constitution to the voters of Denmark for ratification. However, after voters voted down the Constitution in both the French and Dutch referendums before the Danish vote could take place, Danish prime minister Anders Fogh Rasmussen indicated that the referendum would be cancelled.
