The party is marked out from the other parties by being Eurosceptic, sharing this position with only the far left, and being the country's most sovereigntist party. The leadership had supported the proposed European Constitution, endorsing it in the 2004 European election, before changing its position in the spring of 2005 under pressure from party members. In its criticism of the EU, the party puts emphasis on the democratic deficit and transparency. However, in heavily pro-European Luxembourg, the ADR had always fared worse in European elections than on national elections, which were held on the same day. This was the case only until 2014, when the party achieved a slightly better score than it had in the early 2013 national elections, managing to beat the LSAP in the majority of communes.
