Nearly two-thirds of Poland's citizens oppose joining the debt-laden eurozone, according to a poll published on Tuesday.
Only 32 percent of those questioned said they wanted to adopt Europe's single currency, while 62 percent were against and the remainder had no opinion, the leading daily Rzeczpospolita said.

"The climate isn't right today in Poland for eurozone entry," Prime Minister Donald Tusk told reporters in Warsaw Tuesday, while insisting it remained a goal for his centrist government.
The ex-communist nation of 38 million people is obliged to adopt the euro under the terms of its 2004 EU entry agreement, which did not specify an accession deadline.
Poland had adopted a wait-and-see approach to swapping its zloty for the euro as the eurozone tries to resolve its protracted debt crisis.
Tusk's centrist government has put off practical steps towards joining the euro until after elections in 2015.
With the conservative opposition against the move, the government lacks the two-thirds parliamentary majority required to make the constitutional change to adopt the euro.
Tusk said Tuesday he would be in favour of a parliamentary manoeuvre that would allow Poland to settle the eurozone decision through a referendum.
"And that's for an obvious reason: fewer votes are needed to win a referendum," he said.
