European Commission
The commission is made of 27 people, one from each of the countries in the EU. One of these people is the President, who was chosen by the Council and Parliament, he decides (with each country) who the other members are and what they do. Each one has a different job, such as looking after industry or trade. If they do not do their job properly, the President can remove them. If he does not, or if the President does not do his job, the Parliament can remove the whole Commission from their jobs (this only happened in 1999).
