Bosnia's Serb Republic is expected to bar the state police and judiciary from operating on its territory on Thursday, a day after a state court ordered the Russian-backed separatist Serb president to step down for defying an international peace envoy.

Bosnia's autonomous Serb region passed legislation barring the state police and judiciary from its territory after a court sentenced its separatist leader Milorad Dodik to a year in jail and banned him from politics for six years.

Bosnia's Serb political leader Milorad Dodik was sentenced to one year in prison and banned from holding public office for defying the decision of the fragile country's international peace representative.
