Reports from Zimbabwe's capital Harare indicate that police have sealed off roads near the Constitutional Court, where Nelson Chamisa the leader of the MDC Alliance is challenging the results of the election won by President Emmerson Mnangagwa.

Chamisa, 40, alleges that the Zimbabwe Electoral Commission (ZEC) conspired to rig the election in favour of Mnangagwa. He has assembled a team of lawyers including top South African advocates Dali Mpofu, Tembeka Ngcukaitobi, Tapiwa Shumba and Jeremy Gauntlett.

However, the high profile team expected to lead Chamisa's legal assault on the electoral process that he says was rigged in favour of ZANU PF and its 75-year-old leader, Mnangagwa, was yet to receive work permits.

Police have warned people not to carry recording devices into the court.

At least six people were shot dead in the streets of Harare by the army before ZEC announced the disputed results. Many others were injured in the ensuing melee.

The court is expected to deliver its judgment on Friday.
