How does the European Parliament confirm the incoming Commission?

"Knowing how the European Parliament works it’s almost inevitable that it will try to challenge one candidate," Agata Gostyńska-Jakubowska, a senior research fellow at the Centre for European Reform told Euronews.

"One of the objectives of this whole exercise is to show its teeth and to show the Commission President-elect that the European Parliament wants to have a say on the makeup," Gostyńska-Jakubowska said.

"At the end of the day, the European Parliament has a certain leverage vis à vis the European Commission President... it seems to me they will be keen to use it," she added.
