"The group of leaders proposed for the top positions of the European Union, such as [Ursula] Von der Leyen, [Charles] Michel, [Christine] Lagarde and [Josep] Borrell is really balanced, with much experience, and truly committed Europeans,” Barroso wrote in a Twitter post. “I am confident that they will offer real leadership for a stronger EU.”

Two women and two men – three of whom are from EU founding countries (Germany, Belgium and France) – were on Wednesday provisionally appointed by the European Council to occupy the EU’s top institutional positions.

The decision was announced after a marathon bargaining session in Brussels that took three days, with several interruptions, in which the heads of state and government of the 28 EU member states hammered out an agreement.

They appointed Germany’s von der Leyen for president of the commission, Belgium’s Charles Michel for president of the European Council, Spain’s Josep Borrell for EU High Representative for foreign policy and France’s Christine Lagarde for president of the European Central Bank.

The appointments must be approved by the European Parliament to take effect.
