Jean-Claude Juncker, the centre-right European People's Party's choice to head the European Commission, said Sunday the grouping was winning European Parliament elections, giving it the right to choose who takes the post. "The EPP is winning the European elections and accordingly claims the presidency of the European Commission," Juncker said in a message on Twitter. The five main political groups in the outgoing Parliament, where the EPP was the largest, named candidates to the post which will be decided by EU leaders after taking into account the outcome of the elections.
