Robert Mugabe's Zanu-PF party is already claiming victory in Zimbabwe's elections.
The official results aren't due until this weekend, at the earliest.
Mugabe's rival - Morgan Tsvangirai - says there's been a "monumental fraud" and there are widespread claims of vote rigging.
Official monitors say voting was 'orderly and peaceful'.
Thanx Zim for coming out in such huge numbers. Lots of moves to subvert the will of the people today but we are winning this. #crossover

Tsvangirai's party, the MDC, were putting on a show of confidence, though no-one's managed to shift Mugabe from the top position since he came to power:

But there were allegations of election irregularities, in a poll that could bring to an end 33 years of Mugabe rule:
#Zimbabwe MDC alleges multiple "vote rigging shenanigans by ZANU PF" including discovery of extra polling station not on official list.

@RebuildZimbabwe yes - there are several different stages in the process (which change according to area) where results get manipulated.
