The idea of an NPE began when Oswald Mosley launched his Europe a Nation campaign after World War II at a time when contemporaries such as Jean-François Thiriart were also becoming interested in Europeanism.
[3] The European Declaration at Venice was released on 1 March 1962 and contained the following ten aims: The conference also decided that each member party should seek to change its name to NPE or the local equivalent, that the motto of the new group should be 'Progress - Solidarity - Unity' and that the Flash and Circle should serve as the emblem of the movement.
Both the Italian Social Movement and the National Democratic Party of Germany, successor to the Deutsche Reichspartei, refused to change their name and only set up a permanent liaison office.
[6] Mosley meanwhile had little day-to-day contact with the Union Movement from his base in France and he retired from politics altogether after his poor showing in Shoreditch and Finsbury at the 1966 general election, effectively drawing the curtain on the NPE.
[8] A group called European Action continued to agitate for the aims of the NPE until the 2010s through its newspaper of the same name, edited by Robert Edwards, although it was an almost exclusively British movement.
