The Zimbabwe Electoral Commission has begun the announcement of official results of presidential and legislative elections by releasing the first batch of parliamentary seats results.
A delay in issuing the results from elections held on Saturday has led to further accusations of vote-rigging by Robert Mugabe, the country's president.
The opposition Movement for Democratic Change party, led by Mugabe's old rival Morgan Tsvangirai, won three out of the first six parliamentary seats to be announced on Monday nearly 36 hours after the close of polls.
The other three seats were won by the ruling party, the Zanu-PF.
It is not known yet whether or not Mugabe has retained the presidency.
Utoile Silaigwana, the deputy chief elections officer, declared the results in a nationwide radio and television broadcasts.
He went off the air saying: "We'll be back with you when we have more results."
The election commission had said the delay was due to presidential and parliamentary elections being held at the same time, but the piecemeal announcement has left observers questioning the transparency of the process.
Some election observers have said that initial results were known by 11pm (2100 GMT) on Saturday night, just four hours after polls closed.
In previous elections, partial results have been announced within hours of voting ending.
The MDC won the first seat to be declared, in a new constituency called Chegutu West, which is about 100km west of the capital, Harare.
A total of 210 parliamentary seats are due to be declared.
The opposition has already claimed victory in the vote that posed the biggest threat ever to Mugabe's 28-year rule.
