Brexit has an ensemble cast, and many of those figures on the EU side may not be too familiar to British people trying to follow negotiations.

Here’s a primer of the main European politicians and officials leading the bloc’s negotiating effort, and those who have key roles in the process.

Michel Barnier

The European Commission’s chief negotiator. A former French foreign minister, Barnier hails from the continent’s pro-European centre-right. He is the EU’s face in negotiations and has been given the sole authority to negotiate for the bloc – sometimes to the chagrin of the British side, who would rather bypass him. Takes his negotiating guidelines from the European Council (the 27 other EU leaders) and reports back to them regularly so he can speak with a consensus behind him.

The president of the European Commission – the EU’s executive, based in Brussels. Was appointed in 2014, his term ends after the next European Parliament elections in May. Mostly leaves Brexit to Barnier, but makes occasional interventions. Centre-right pro-European and former prime minister of Luxembourg.

Leo Varadkar

Ireland’s prime minister, a role known in the Irish language as the Taoiseach. Has a key role because of the importance of the Irish border issue, and backs the EU line on the so-called backstop, at least in public.

The president of the European Council – representing the 27 national leaders collectively. Is supposed to consult with the national leaders before making statements, and try and reflect their views. A former Polish prime minister and sports fanatic, has often presented himself as a calming influence on talks, expressing optimism that a deal can be reached.

Guy Verhofstadt

The Brexit coordinator for the elected European Parliament. Staunchly pro-EU and the leader of the liberal group in the parliament, he acts as a spokesperson for the body on Brexit issues. Consults with and leads the parliament’s Brexit taskforce, a committee of MEPs representing the non-European sceptic groups. Draws up motions about Brexit for MEPs to vote on, which are usually passed with a huge majority. Outspoken and often an outrider for the EU. Former Belgian prime minister.

Michel Barnier’s second in command, Weyand does the heavy lifting in negotiations and has a firm grasp on the technical detail. Tends to shun the limelight but can be found in Brussels explaining the complicated aspects of talks.

Antonio Tajani

The president of the European Parliament. Has taken somewhat of a backseat in the media compared to showman Verhofstadt on the Brexit issue, but still has an important role in representing the Parliament’s interests – for instance in meetings with leaders at the European Council. A former Italian EU commissioner, associated with Silvio Berlusconi’s Forza Italia.

Germany’s chancellor, leading the country’s government. Rarely intervenes on Brexit, but her role as chief of Europe’s largest economy gives her huge clout when she does. A centre-right Christian Democrat who values stability – and Germany’s central role in the European project.

Emmanuel Macron

The French president. A pro-European liberal centrist, Macron has taken one of the harder lines in Brexit talks of any national leader. Said to view Brexit as a form of populism akin to the right-wing governments springing up in the east of the continent, has been so far-successful in convincing other EU leaders not to compromise their principles too much. Accused Brexiteers of being liars.

Simon Coveney

The Irish foreign minister, often seen representing Ireland’s interests abroad with Varadkar is doing something else. Knows Brussels well as a former MEP. He is also the Tánaiste – Ireland’s deputy prime minister – a sign of his senior role.
