Poland's pro-business prime minister has faced off against her main challenger in a debate ahead of general elections this weekend — the first time two women are the top two contenders to lead the country.

The debate took place Monday evening between Prime Minister Ewa Kopacz of the pro-European Civic Platform party and Beata Szydlo of the conservative and populist Law and Justice party, which is significantly ahead in the polls.

Kopacz said a victory by Law and Justice, which promises more spending and tax cuts to help struggling Poles, would threaten Poland's finances and lead to a crisis similar to that in cash-strapped Greece.

Szydlo, in turn, accused the current government of being corrupt and ineffective and said it has failed to fight for Polish interests in Europe.
