The present accord concerning the new EU treaty is exclusively of political nature, Polish Prime Minister Jaroslaw Kaczynski said in Przemysl, south-eastern Poland on Monday.
"No other agreement has been reached yet," Polish PAP news agency quoted Kaczynski as saying.
Kaczynski stressed that Poland did not undermine the agreement but wanted it "to be written in its entirety and not without one but substantial element."
Kaczynski said that as regards the ratification of the treaty reforming the EU "the constitution envisages two options and we can choose each one."
He added that the treaty may be ratified by the parliament or via referendum.
Kaczynski said he hoped that the conference, held under the EU presidency of Portugal that started on July 1, would be an honest and smoothly carried out process.
The new EU treaty known as the Reforming Treaty is to be approved by the Inter-Governmental Conference by the end of this year. It is to replace euro-constitution rejected by France and Holland.
