The Lisbon Treaty, entered into force on 1 December 2009. It strengthens the European Parliament, gives national parliaments more responsibility in determining the course of European policy, as well as allowing EU citizens the power of initiative. The Lisbon Treaty enhances European Parliament’s powers as a fully recognised co-legislator with increased budgetary powers. It also gives Parliament a key role in the election of the President of the European Commission.
