MOSCOW (Sputnik), Yulia Shamporova — Polands increase in military build-up could potentially lead to an intervention in the current Ukrainian conflict, head of the Polish party Zmiana (Change), Mateusz Piskorski told Sputnik Thursday.

On Tuesday, Polish President Bronislaw Komorowski announced that Warsaw is planning to buy US Patriot surface-to-air missiles in light of a perceived Russian threat.

"Poland is investing in offensive weapons which means that it does not build its own security, its own defense system, but it builds a kind of army units that would be ready for intervention and aggression abroad. In the context of the Ukrainian conflict, it is quite obvious that potentially Polish force could be used in Ukraine," Piskorski said.

He noted that Polands militarization contradicts the countrys national interests and will drain resources from its budget.

"Probably, Poland will have to sign several bills about financing all these programs of Armed Forces organizations which will rise and increase the already existing debt of Poland, which of course, influence the whole political and economic situation in the country," Piskorski said.

He added that currently different social groups in Poland are raising concerns about the authorities plans to raise the military budget instead of addressing important social issues.

In mid-April, the Stockholm International Peace Research Institute (SIPRI) said that the conflict in Ukraine prompted many European countries, including Poland and the Baltic states to boost their military spending. According to SIPRI, in 2015 Poland is to increase its military budget by 19 percent to $9.9 billion.
