Former Democratic Republic of Congo President Joseph Kabila’s coalition has won a clear majority in senate elections, officials told Reuters news agency.
Mr Kabila’s Common Front for Congo (FCC) coalition won more than 80 of 108 seats in the senate, or upper chamber, Felix Momat, a senior FCC official is quoted as saying.
The electoral commission has not published the official result yet.
Only the provincial assembly members are allowed to vote in this poll and the overwhelming majority of those are from the FCC.
The election took place amid unprecedented public allegations of corruption and vote buying.
At least seven candidates have withdrew from the race in protest of the alleged corruption, they accused provincial MPs of demanding payments of sums as high as $50,000 (£37,723) in exchange for their votes.
Congo’s general attorney Flory Kabange Numbi earlier wrote to the electoral commission asking for the postponement of the senatorial vote so that police can investigate these allegations.
His request was not accepted by the electoral commission.
Mr Kabila did not stand for the last election. Opposition leader Félix Tshisekedi won but observers say this result will undermine Mr Tshisekedi’s ability to govern independently.
