Donald Trump’s victory in the US presidential elections is good news for Poland, a senior official from the ruling conservative Law and Justice (PiS) party has said.

The head of the PiS parliamentary caucus, Ryszard Terlecki, told Polish Radio: “We are convinced that Polish-US relations will be better than up till now.”

He added: “America is our most important political partner, our most important ally, and we are confident that this is a good choice for Poland.”

But according to the Civic Platform (PO), Poland’s largest opposition party, Trump’s victory means “great uncertainty”.

Party spokesman Jan Grabiec told Polish Radio: “We don’t know anything about the shape of US foreign and security policy and there can be no efficiently functioning NATO without an active commitment of the United States.”

He added that if the United States moves towards isolationism and focuses solely on its own problems, rather than those of worldwide significance, there will be a greater sense of uncertainty and a potential destabilization of world peace and order.

“The consequences can be incalculable”, he added.
