Polish president accepts resignation of Brussels-bound PM Tusk
The president will invite parliamentary speaker Ewa Kopacz, the ruling coalition's candidate for prime minister, to meet him for talks on forming a new government.
Under Poland's constitution, the president nominates a prime minister. The prime minister-designate forms a new cabinet which is then submitted to a vote of confidence in parliament. The ruling coalition has a small majority in the legislature.
