The faction of Zimbabwe's opposition Movement for Democratic Change faction led by Arthur Mutambara on Friday challenged reports it has agreed with the rival faction of Morgan Tsvangirai to unite behind Tsvangirai as sole presidential candidate in 2008.

Mutambara faction spokesman Gabriel Chaibva said the formation for the moment is limiting itself to reconfirming an internal decision reached in July to the effect that it could conceivably support Tsvangirai as opposition candidate within a coalition.

But for the moment it will go no further than to say that it agrees the presidential candidate should come from the Tsvangirai opposition faction.

Chaibva told reporter Patience Rusere of VOA's Studio 7 for Zimbabwe that overtures to the Tsvangirai camp in July as to naming a single presidential candidate drew no response, but said that his party is open to Tsvangirai as opposition candidate.

The Tsvangirai faction said no decision has been reached yet on the question.

Spokesman Nelson Chamisa said his grouping does believe in one candidate, but said he would not go into the particulars of the matter in the media.
