Bettel's predecessor and current president of the European Commission, Jean-Claude Juncker, sent the re-elected prime minister a personal letter of congratulation.

Juncker added "Cher Xavier" in handwriting to the letter sent to Bettel, who was sworn in as prime minister for a second term on Wednesday.

He congratulated Bettel both in his capacity as president of the European Commission and personally for having formed a second government of Luxembourg. Juncker expressed his certainty that Bettel's government would contribute successfully to advancing the European project.
