According to the pro-Yanukovych "Segodnya'" newspaper the inevitable 'source close to Yanukovych' exposed the president's calculations by claiming:
Polish president Komorowski is not interested in Tymoshenko herself - he is perfectly well aware that by signing a gas contract in 2009, Yulia T. worked for the benefit of Russia as well as for herself in the presidential race, but this topic had to be raised to take account of a strong BYuT lobby the European Parliament.
The only important thing is which argument tips the scales - the need to mitigate the situation around Tymoshenko, or the need to draw Ukraine into the EU because of the serious pressure being strongly applied by Russia onto Ukraine.
For Komorowski the choice is clear already - drawing Ukraine into the EU is more important than Tymoshenko, and his opinion as the current head of the EU is influential, but it is also clear that there are more powerful heads of state in the EU.
However the Polish President will make every effort, because he understands that Ukraine will either receive an association agreement under his Presidency, i,e. by the end of 2011, or it will it be postponed indefinitely.
At the same time, a 'Segodnya' BYuT informant claims that it was made clear to the president of Ukraine in Gdansk that the EU integrates only with democracies, or those countries moving toward democracy; and a country where the opposition leader is behind bars can not be considered democratic.
Neither of these viewpoints are strictly correct - no leader is above the law.
The criminal cases against both Tymoshenko, and Lutsenko, are fundamentally weak - that is the reason why they are seen to be politically motivated. In countries with independent judiciary there would have been no trial in either case, or the trials would have collapsed very quickly.
Furthermore, even though these trials are being carefully scrutinised, they have been conducted from the very beginning in a completely shambolic and prejudicial manner, so any verdict cannot be considered sound.
