Jean-Claude Juncker, the President of the EU Commission, spoke in the European Parliament earlier as his term comes to an end. Ursula von der Leyen will take up the role on November 2, CNN reports.
Juncker noted that he's spent a lot of his time in the position talking about one topic.
"In truth, it has pained me to spend so much of this mandate dealing with Brexit when I have thought of nothing less than how this union could do better for its citizens," he said.
"A waste of time and a waste of energy," Juncker added.
"I will always regret the United Kingdom’s decision to leave the Union. But at least we can look at ourselves in the eye and say that we have done all in our power to make sure that this departure is orderly," Juncker added.
