Zimbabwe's rival opposition factions say they have reunited, declaring they have a majority in parliament.

The announcement was jointly made by Movement for Democratic Change (MDC) leader Morgan Tsvangirai and Arthur Mutambara, whose faction split in 2005.

The final results of parliamentary and presidential polls have still not been published - more than four weeks after the elections.

Mr Tsvangirai says he beat President Robert Mugabe outright in the polls.

But independent monitors and Mr Mugabe's allies say that neither candidate passed the threshold of more than 50% of the vote required to be declared the president.
