Poland's prime minister-designate has named a new foreign minister to replace Radek Sikorski, who has been a forceful voice internationally on the conflict in Ukraine.

Ewa Kopacz replaced Sikorski with Grzegorz Schetyna, 51, a former interior minister and deputy prime minister who most recently has headed the parliamentary commission for foreign affairs.

Kopacz, who takes over from Donald Tusk, announced the replacement Friday as she revealed the make-up of Cabinet that includes many of Tusk's ministers but some replacements.

Some political observers had said it would be best for Sikorski to remain foreign minister to give continuity to Poland's foreign policy as a time of conflict in neighboring Ukraine.

Tusk stepped down recently after being elected to head the European Council in Brussels, a job he takes up Dec. 1.
