On 24 April 2003, the Convention Praesidium
proposed that the enlarged Union should have a President of the
European Council and a Foreign Minister. Other proposals for a
new institutional architecture of the EU include downsizing the
Commission to 15 members, setting up a Congress of national and
EU parliamentarians, making the number of members of parliament
more proportional to the size of countries' populations and
changing the qualified majority voting system so that such a
majority shall consist of the majority of Member States,
representing at least 60 percent of the Union's
population.
