BRUSSELS (AP) — The Latest on the European Union summit (all times local):

10:45 a.m.

A European Union official says leaders are moving closer to filling a handful of the block’s key posts.

The official say Dutch socialist Frans Timmermans is in prime position to succeed Jean-Claude Juncker as head of the European Commission.

The high-ranking diplomat involved in the talks says that the Christian Democrats would have Bulgaria’s Kristalina Georgieva follow Donald Tusk as head of the European Council, which coordinates policies of member states and organizes summits.

The official spoke on condition of anonymity because the 28 leaders had not yet reconvened for the formal summit where they should confirm the jobs.

European Union officials say leaders pulled an all-nighter at a summit but failed to agree on the list of candidates for the bloc’s key posts, with the marathon talks entering a second day.

The leaders trickled in for bilateral contacts through Sunday before officially convening at around 8 p.m. Sunday. They have been locked in talks ever since amid deep divisions over how to best balance political, geographic and gender considerations among the 28 member nations.

With the selection process bogged down for the second EU summit meeting in a row, the leaders were still considering Dutch socialist Frans Timmermans to replace Christian Democrat Jean-Claude Juncker as president of the EU’s powerful executive arm, the European Commission.
