Kallas has the fewest supporters.

This is written by Politico. Details:

🟩 the first camp — supporters of the President of the European Council António Costa. They believe that this position makes him the natural candidate for the role of EU representative;

🟩 the second — for representatives from France and Germany. Both countries do not want to yield places at the negotiations to Brussels. They are unlikely to welcome an agreement that would give it a monopoly on representing Europe, sources said;

🟩 the third camp — supporters of Kaja Kallas. But her hardline position towards Russia may cause rejection by the Kremlin and turn her candidacy into a problem, some European diplomats believe.

“The question of who speaks on behalf of Europe has never been so important, but the EU has no answer”, the article concludes.
