Usually, Intergovernmental Conferences to change the EU Treaties receive quite some attention of the continent.
This time, it is different:
Almost unnoticed, the Spanish EU-Council Presidency has invited to an Intergovernmental Conference on the level of Permanent Representatives (that is, the ambassadors of the EU member states) for next Wednesday, 23 June 2010, to agree on the changing of the EU Treaties to allow 18 new members of the European Parliament to officially take part in the EP's work.
The exact distribution of these 18 can be found in the respective additional protocol laid out in European Council document EUCO 11/10 (page 11).
Since this will be a Treaty change, all EU member countries will need to ratify it according to their national procedures.
