Schetyna’s message
Those, who believed that one party will dominate Poland, are wrong. We will not have a Budapest in Warsaw!
“This was and is a celebration of democracy. This was a tough campaign and it was not an equal fight, there were no rules. We did not feel that our opponent used fair methods. But we believe in our victory in the Senate. The next elections are ahead of us – the presidential elections in half a year and we will win. Those, who believed that one party will dominate Poland, are wrong. We will not have a Budapest in Warsaw!” Schetyna proclaimed.
The official election results are expected to be published on Tuesday, the 15th of October at the latest.
