The 2014 Party of European Socialists presidential primaries is the selection process by which the members of the Party of European Socialists (PES) and will choose the PES candidate for President of the European Commission ahead of the 2014 European elections. Context Partly due to reluctance among some national delegations, the Party of European Socialists (PES) did not present any candidate for the post of Commission President to the European elections of June 2009. Following the disappointing results of PES member parties during these elections, however, the European People's Party (EPP) remained the largest party in the European Parliament, and their candidate José Manuel Durão Barroso was re-elected as Commission President. In light of this, the PES Congress of Prague of December 2009 made the decision that PES would designate its own candidate before the 2014 European elections. A few months afterwards, in June 2010, several PES supporters launched an online campaign for a PES primary which rapidly gained momentum on social networks. Led by Desmond O'Toole, José Reis Santos and Arthur Colin, the campaign managed to convince the PES Council meeting in Warsaw in December 2010 to set up Working Group "Candidate 2014" in charge of proposing a procedure and timetable for a "democratic" and "transparent" designation process. The Council accepted to "bring on board all PES member parties and all levels within the parties" in the selection process. One year later, basing on the working group's conclusions, a PES Council gathering in Brussels in November 2011 decided that PES would designate its candidate for Commission president through primaries taking place in January 2014 in each of its member parties and organisations, before a ratification of the results by an Extraordinary PES Congress in Rome in February 2014. Process The general procedure of the PES primary is detailed in the PES Resolution "Selecting our common candidate in 2014" adopted by the PES Council on 24 November 2011. Six months before the process is launched, the timetable of the primary will be readjusted by the PES Presidency according to the exact date decided by the Council of the EU for the 2014 European elections. Nomination process First, a nomination process will determine which candidates are eligible for the primary. It follows three steps: 1–31 October 2013: Opening of nominations. Candidates will have to send their candidacies, one letter of nomination, and five letters of support to the PES secretariat. Anyone
