On 8 June 2010, the ADR joined the Alliance of Conservatives and Reformists in Europe, a Euro-Realist Europe-wide political party. In the snap-election of 2013, the ADR once again fell in their share of the vote, from 8.14% to 6.64%. However, they did manage to regain one seat, having fallen to only two MPs after the defections of Jacques-Yves Henckes and Jean Colombera. The former sat out the 2009-2013 legislative period as an independent, the latter founded the Party for Full Democracy. Roy Reding regained the mandate in the Centre district, putting the party back at 3 mandates.
