Members of Poland's newly elected right-wing parliament are being sworn in, part of a major power shift in the European Union's largest eastern member.

For the first time since Poland threw off communism in 1989, the country has a parliament with no left-wing representation. In another first, a single party — Law and Justice — won enough votes for a parliamentary majority, putting it in a strong position to put through its policies without having to make compromises with a coalition partner.

The party is strongly pro-U.S. and pro-NATO but more skeptical of the European Union than the outgoing centrist Civic Platform party.

Members of the 460-member Sejm, or lower house of parliament, were standing up one by one to take the oath of office in the assembly hall Thursday.
