For PiS, that means playing on fears of abandoning the Polish zloty for the euro, rising energy prices and the impact of the EU’s climate policies on farmers.

He said he believed that having its own currency, the zloty, helped Poland avoid recession during the global financial crisis and to weather other shocks.

"The zloty should continue to strengthen further in the near-term in anticipation of improving relations with the EU that will help to support growth and attract capital inflows."

Poland’s currency, the zloty, was slightly stronger after the rate cut.

The weakening of the zloty will cause imported goods to become more expensive for Polish consumers.
