WARSAW, Poland (AP) — Prime Minister Donald Tusk said Tuesday that Poland’s parliament will hold a confidence vote on his government on June 11, as the country faces a “new political reality.” He called for the vote after his political ally, the liberal Warsaw mayor, lost Poland’s weekend presidential election to conservative Karol Nawrocki.

The victory of Karol Nawrocki, who is backed by the previous right-wing governing party, will complicate Prime Minister Donald Tusk’s efforts to advance his liberal agenda.
