Eighth European Parliament in the context of "2019 European Parliament election"

The Progressive Alliance of Socialists and Democrats (S&D) is the political group in the European Parliament of the Party of European Socialists (PES). The Progressive Alliance of Socialists and Democrats was officially founded as a Socialist Group on 29 June 1953, which makes it the second oldest political group in the European Parliament after the European People's Party Group (EPP Group). It adopted its present-day name on 23 June 2009. Centre-left in orientation, the group mostly comprises social democratic parties and is affiliated with the Progressive Alliance and Socialist International.

Until the 1999 European Parliament elections, it was the largest group in the Parliament, but since then it has always been the second-largest group. During the eighth EU Parliament Assembly, the S&D was the only Parliament group with representation from all 27 EU member states. In the current EU Parliament the S&D is currently composed of 136 members from 25 member states.

Renew Europe (or simply Renew) is a liberal, centrist to centre-right, pro-European political group of the European Parliament founded for the ninth European Parliament term. The group is the successor to the Alliance of Liberals and Democrats for Europe (ALDE) group which existed during the sixth, seventh and eighth terms from 2004 to 2019, and under a variety of other names in earlier Parliaments. Renew Europe in the European Committee of the Regions is the sister group of Renew Europe.

Identity and Democracy (ID; French: Identité et démocratie) was a political group of the European Parliament during the Ninth European Parliament term, launched on 13 June 2019. It comprised far-right, right-wing populist, Eurosceptic and nationalist national parties from six European states. It was the successor to the Europe of Nations and Freedom group formed during the eighth term and almost all of its members merged into the Patriots for Europe group formed during the tenth term.

Europe of Nations and Freedom (ENF; French: Europe des nations et des libertés, ENL) was a far-right political group that operated in the European Parliament between 2015 and 2019. It was composed of 37 MEPs and only existed during the European Parliament's 8th term. Most of its MPs were members of the Movement for a Europe of Nations and Freedom political party.

Ideologically, ENF was right-wing populist and Eurosceptic. Its members included far-right parties such as French National Front (known as National Rally after 2018), Italian Lega Nord, Dutch Party for Freedom, and Vlaams Belang. After the 2019 European Parliament election, ENF was transformed into the Identity and Democracy group.
