The opposition Movement for Democratic Change says a court in Zimbabwe has overturned a police ban that prevented a major rally before next week's presidential run-off election. The party said that the decision would allow the MDC to hold its rally in the capital Harare tomorrow. Peter Biles reports from Johannesburg.

Zimbabwe's MDC opposition has to apply for official permission to stage election rallies or public meetings, frequently the police blocked such events. But following a court application, the opposition says it's been allowed to hold a major event in Harare on Sunday. The MDC leader Morgan Tsvangirai is expected to attend. This week in the face of a crackdown by the state, the MDC was complaining that it was being forced to campaign for the second round of the presidential election contest in conditions of virtual secrecy. The party is expected to make it clear within the next couple of days whether or not it will take part in the election run-off.

Police in Macedonia have arrested a journalist on suspicion that he was behind three murder cases he'd been reporting on. The journalist, Vlado Taneski, is accused of kidnapping, abusing and raping three women. Andrew Craig reports.

Vlado Taneski is the correspondent for a Macedonia national newspaper in the town of Kicevo. A police spokesman said suspicion fell upon him when his reports included details of murders that the police themselves had not disclosed. The three cases involved elderly women who are raped and mutilated, then naked bodies were cut into pieces and dumped in plastic bags. The spokesman said Mr. Taneski's DNA appeared to be linked to the murdered women. He is also suspected over the disappearance of another woman who has been missing for several years. The police say that all the women bore similarities to Mr. Taneski's late mother with whom he had had a troubled relationship.
