The Democratic Republic of Congo’s constitutional court has disqualified 23 opposition MPs who were elected in December.
Report says a total 33 MPs were invalidated by the court.
It did not disclose its reasons, but the court is meant to make judgements on votes recounted after complaints, our correspondent reports.
Reports also say that six out of the nine judges that made the decision were nominated while former President Joseph Kabila was in power.
It adds that the opposition alliance, known as Lamuka, has suspended its participation in parliament, saying that the rule of law has been “assassinated”.
In January, opposition candidate Felix Tshisekedi was sworn in after winning the presidential election.
At the time he denied accusations that the election was fixed and that he had made a power-sharing deal with the outgoing president.
