Alternative Democratic Reform Party

The Alternative Democratic Reform Party (ADR; Luxembourgish: Alternativ Demokratesch Reformpartei, French: Parti réformiste d'alternative démocratique, German: Alternative Demokratische Reformpartei) is a conservative and mildly populist political party in Luxembourg. It has five seats in the sixty-seat Chamber of Deputies, making it the fourth-largest party. In 2024, the party received its first seat in the European Parliament.

The party was founded in 1987 as a single-issue party from demanding equality of state pension provision between civil servants and all other citizens. In the 1989 election, it won four seats and established itself as a political force. It peaked at seven seats in 1999, due to mistrust of politicians failing to resolve the pensions gap, before falling back to three, then coming back up to four then five. Its significance on a national level makes it the most successful pensioners' party in western Europe.

Political success has required the ADR to develop positions on all matters of public policy, developing an anti-establishment, conservative platform. It has adopted economic liberalism, filling a gap vacated by the Democratic Party. It is the largest party in Luxembourg to take a Euro-realist/softly Eurosceptic line, and is a member of the Alliance of Conservatives and Reformists in Europe. The ADR wishes to implement Swiss-style direct democracy and advocates and promotes intensely the preservation and use of the Luxembourgish language in state institutions and society. The ADR is most often characterised as being a national-conservative party.
