The radical right has never been particularly strong in Luxembourg. The National Movement was an unsuccessful far right party which dissolved after failing to enter parliament in the late 1980s and mid 1990s.

The most right-wing party in Luxembourg today is the Alternative Democratic Reform Party (ADR). It was founded in 1987 as a single-issue party, focusing on pension reform, but later broadened its politics. The ADR is economically liberal while conservative on social issues. It is the most eurosceptic party in the country, except for DL. The ADR has been represented in parliament since 1987 but has never been part of any government. 

ADR is classified as a right wing populist party in several studies and is included in this index as well. It clearly contains many elements of an anti-establishment party. Even though the ADR is more eurosceptic and critical of immigration than other parties in Luxembourg, it should be underlined that it is quite moderate even on those issues compared to other national conservative parties in Europe. The ADR wants to strengthen the status of the Luxembourgish language and wants deep institutional reform, favouring a Swiss-style direct democracy. During the pandemic, it was very critical against the government, arguing that the restrictions constituted unacceptable limits to personal freedom. 

The current leader of ADR, Fred Keup, has been described as more radical on immigration and multiculturalism than his predecessor. Keup was the informal spokes-person of the successful no-campaign in the 2015 referendum on whether to extend voting rights to non-citizens, a major victory for the party. Keup was elected party leader in 2022. His profile on X contains one message: “stop woke ideology”.
