The latest in a series of debates among candidates for the post of next European Commission president has taken place in the European Parliament in Brussels.

Five political figures from across Europe and across the political spectrum appeared in the televised debate ahead of the upcoming Euro elections which has an electorate of 390 million voters.

The participants were Martin Schulz, the President of the European Parliament, who represented the Socialists and Democrats and Jean-Claude Juncker of the European Peoples' Party.

Other participants included Guy Verhofstadt of the Liberals and Democrats; Alexis Tsipras, the Party of the European Left nominee for President of the European Commission and Ska Keller of the Greens.

Tonight's debate, co-presented by RTÉ's Conor McNally, gave citizens the opportunity to put their questions to the five candidates seeking the EU's top job.

Voters helped shape the show and the agenda by offering their questions and comments via social media.
