 The Commission employs 25,000 people and the Parliament employs about 6,000 people.Because of this concentration, Brussels is a preferred location for any move towards a single seat for Parliament.Despite it not formally being the "capital" of the EU, some commentators see the fact that Brussels enticed an increasing number of Parliament's sessions to the city, in addition to the main seats of the other two main political institutions, as making Brussels the "de facto" capital of the EU.
