I should have said the last scheduled national parliamentary elections (that's 3 qualifiers for ya!).

There will also be a few elections in some of the states of Germany, which could be very important for the balance of power internally in Germany. But the people in the Council of Ministers and in the European Council will stay the same for over a year and three months.

(More qualifiers: Depending upon the date of elections in Greece/Spain, and if no government falls. Plus Slovenia also elects a president in December this year but I don't know what his role in the EU institutions is, more like the French president (all-decisive) or more like the German president (none at all))
