In the past 

The European Parliament has evolved significantly over the years, steadily accruing additional responsibilities and gaining in importance. While its predecessor the Assembly was merely there to supervise, the Parliament today is the only directly-elected EU institution, charged with representing people’s interests. In addition to shaping and deciding on new legislation, it is also responsible for scrutinising the EU institutions and promoting human rights in and outside Europe. In this section you will find out more about how the Parliament has developed over time.
