The center-right European People's Party (EPP) — the largest faction in the European Parliament — has picked Manfred Weber, its German parliamentary party leader. He has the backing of Chancellor Angela Merkel. Though considered the front-runner, Weber is little known on the international stage, and his language skills are considered poor.

Frans Timmermans, the European Commission's first vice president, will lead the campaign for the Progressive Alliance of Socialists & Democrats (S&D). Weber's main rival promises to bring the bloc closer to ordinary voters at a time when Britain's looming exit is one factor behind the nationalist movements across the EU.

Margrethe Vestager, 51, is one of seven lead candidates for the Alliance of Liberals and Democrats. As the current EU commissioner for competition, the Danish MEP has taken on corporations like Apple, Amazon and Google parent Alphabet. It's also been said that she served as the inspiration for the main character in <i>Borgen</i>, a Danish series where a woman becomes Denmark's first female leader.

The third-largest group in the EU Parliament, the European Conservatives and Reformists (ECR), has just one candidate: Jan Zahradil, chairman of the Czech ECR delegation. Zahradil, 65, is affectionately known as "Forrest Gump" for cycling from Prague to Strasbourg for a session of the European Parliament and for once running 1,300 kilometers (about 800 miles) across the Czech Republic for charity.

The Greens/EFA is the seventh largest group in European Parliament, so the German is a long shot to become European Commission president. The Greens have proposed a job share, with two candidates serving for two-and-a-half years each. The most favorite to join Keller is Dutch lawmaker Bas Eickhout.

The EU's left-wing groups will be headed by Spanish trade unionist Nico Cue and Violeta Tomic (at left). Tomic is a deputy in Slovenia's National Assembly, best known as a TV presenter and actress. She entered into politics in 2014 and has been an advocate for LGBT rights and stronger citizens' rights in Europe. Cue grew up in Belgium after his family was forced to flee Franco's Soain.

"We don't see these people as Muslim refugees. We see them as Muslim invaders," Orban said in a recent interview with German daily Bild newspaper. The 54-year-old prime minister of Hungary added: "We believe that a large number of Muslims inevitably leads to parallel societies, because Christian and Muslim society will never unite." Multiculturalism, he said, "is only an illusion."

When asked by Bild whether it was fair for Germany to accept hundreds of thousands of refugees and migrants while Hungary accepted none, Orban responded: "The difference is, you wanted the migrants, and we didn't." Migration, he said, threatens the "sovereignty and cultural identity" of Hungary.

It was not the first time the Hungarian leader has framed migration as a problem for his country. In 2016, he said that Hungary "does not need a single migrant for the economy to work, or the population to sustain itself, or for the country to have a future." He added: "for us migration is not a solution but a problem ... not medicine but a poison, we don’t need it and won’t swallow it.”

Orban has repeatedly criticized German Chancellor Angela Merkel for her decision to allow over a million migrants into Germany in the summer of 2015. Orban told Bild in early 2016: "If you take masses of non-registered immigrants from the Middle East into your country, you are importing terrorism, crime, anti-Semitism, and homophobia."

Orban has also repeatedly criticized the EU for trying to get member states to share refugees based on national quotas. In a 2015 interview with POLITICO, he suggested the bloc's leaders instead focus more on strengthening the EU's external border. In the same interview, he said: "Of course it’s not accepted, but the factual point is that all the terrorists are basically migrants."

Orban has found allies in other right-wing governments in eastern Europe such as Poland that also oppose the EU's refugee policies. In an interview with Spanish TV channel Intereconomia in 2015, Orban raised fears about integrating Muslim migrants in the EU when he said: "What sort of Europe do we want to have? Parallel societies? Muslim communities living together with the Christian community?"
