"Poland's energy security is the foundation of our sovereignty and the stability of our economy," Nawrocki said after attending the session at the invitation of outgoing president Andrzej Duda.

The comments prompted quick reactions, particularly in light of the fact that Nawrocki allegedly showed up at the meeting with confidence, approaching Polish PM Donald Tusk and acting as if he had already assumed the office.

Polish Ex-Foreign Minister Giertych 'Unbelievable' in Spreading Election Fear, says Leszek Miller
Former Prime Minister Leszek Miller had a sharp message for Civic Coalition politician Roman Giertych, who was trying to question the results of the presidential election. Above a video of a handshake between Nawrocki and Tusk, Miller wrote, "Mr Giertych, your game is in vain.

Capitulation is a fact." His remark reflected on whether endeavours to discredit Nawrocki were out-of-date as well as useless.

The spat is identical to a deepening rift in Polish politics at a time when the new administration prepares to move in, with energy as a bellwether in the ideological battlefield.
