The Ukrainian authorities and opposition, President of the European Parliament (EP) Martin Schulz, along with former Polish President Alexander Kwasniewski and former European Parliament President Pat Cox, who are the members of the EP's observation mission on the trials of former Ukrainian Prime Minister Yulia Tymoshenko and former Interior Minister of Ukraine Yuriy Lutsenko, support the idea of prolonging the mission's work until the signing of the EU-Ukraine Association Agreement.

"The Ukrainian authorities, opposition, President Schulz, and we ourselves want to prolong the mission," Kwasniewski told journalists after a meeting with Cox, Schulz and Vice President of the EP Jacek Protasiewicz in Brussels on Wednesday.

Kwasniewski added that the mission could be prolonged until the date of signing the Association Agreement at the Eastern Partnership Summit in Vilnius in November 2013.

According to the politician, the proposal will be discussed at the Conference of President of the EP, which includes the EP President and the heads of all political groups of the EP.

"On January 31 we will submit our proposal and a decision will be taken," Kwasniewski said.

While commenting on the situation with former Ukrainian Prime Minister Yulia Tymoshenko, he said that it is hard to predict further development of the situation, as nobody knows what verdict the European Court of Human Rights will announce. At the same time, he stressed that it is important to provide Tymoshenko with the necessary medical treatment.

Speaking about the mission's work in general, Kwasniewski noted that they managed to create "an effective communication channel, a dialogue and build confidence between all sides involved, including the government and the opposition."

The Cox-Kwasniewski mission on the Tymoshenko case started to work in Ukraine on June 11, 2012. Ukrainian Prime Minister Mykola Azarov and EP President Martin Schulz reached relevant agreements.

Later on, the mission's mandate was expanded to the Lutsenko case and the trial on former Acting Defense Minister of Ukraine Valeriy Ivaschenko.

The mission's activities were suspended during the parliamentary elections in Ukraine and resumed after them.
