...demand to change the bloc's proposed voting system is rejected, Prime Ministr Mirek Topolanek said on Wednesday.
The Czech Republic is the only EU member which has been backing the Polish drive to change the voting weights of individual countries.
Topolanek said in a statement that he had a mandate to veto an agreement if individual member states are granted permanent opt-outs of EU policies or if there is a return to "quasi-state" patterns in the treaty.
