“The statement of Radoslav Sikorsky is no different from Russian propaganda,” he wrote on Twitter.

According to Morawiecki, the former foreign minister "should weigh his words."

“I expect these shameful statements to be withdrawn,” he added.

The prime minister also called on the Polish opposition to "dissociate itself" from Sikorsky's statement.

Ronald Reagan White House staffer Paul Craig Roberts has previously suggested that Poland may be preparing to seize western Ukraine.

The director of the Foreign Intelligence Service, Sergei Naryshkin, also spoke about the data regarding Poland's plans for Western Ukrainian lands.
