Order and Justice (Lithuanian: Tvarka ir teisingumas, TT), formerly the Liberal Democratic Party (Liberalų Demokratų Partija, LDP), is a right-wing national liberal political party in Lithuania, though it self-identifies as 'left-of-centre'. It has eleven members of the Seimas. Formed as the 'Liberal Democratic Party' in 2002, the party achieved almost immediate success with the election of leader Rolandas Paksas as President of Lithuania within its first year. The party sits on the centre-right, possesses a radical and anti-establishment identity, and is described as both socially conservative and 'liberal', in line with its original identity. Its support is strongest in the north-west Samogitia region. Its faction in the Seimas also includes the Electoral Action of Poles in Lithuania. The party's two MEPs sit in the Europe of Freedom and Democracy group in the European Parliament, with the party having previously belonged in the now-defunct AEN.
