Head of the European Parliament, Hans-Gert Poettering is coming with a visit to Poland to discuss the issue as well. He has expressed on many occasions his hope that Warsaw will accept the draft of the proposed new treaty.

The draft is to include basic tenets of the bloc's constitution as well as principles of the EU voting system. Poland has already announced that it is determined to fight for the square root principle of voting for citizens of both large and small EU member states insisting that the number of votes each member state has in EU decisions requiring a "qualified majority" be calculated by taking the square root of the country's population in millions.

According to Polish officials, the square root principle in needed in order to prevent the situation in which the biggest EU members states – France, Germany and Britain – have undue influence over the remaining members. Poettering has been against such changes in the draft and while in Warsaw he is to try and persuade Poland’s authorities to give up their demand in this sphere.
