PRAGUE (AP) -- The Czech ruling coalition led by the left-wing Social Democrats has retained its control of Parliament's upper house.
With all votes counted by the Statistics Office Saturday, the Social Democrats won 10 of 27 seats up for grabs in the 81-seat Senate to remain the strongest force in the chamber.
The two other coalition members -- the centrist Christian Democrats and ANO movement -- won four seats each in an runoff ballot held on Friday and Saturday.
After the three coalition parties won a majority in Parliament's lower house in last year's general election, they remain in control of the Senate.
Parliament's lower house dominates the legislative process, but the Senate plays an important role in passing constitutional amendments and approving Constitutional Court judges.
