The full results of Democratic Republic of Congo's election are expected shortly, with President Félix Tshisekedi enjoying a commanding lead over opposition candidates who have demanded a rerun.

President Tshisekedi has received about 72% of the votes announced so far, and appears set for a second term.

The 20 December election was marred by widespread logistical problems.

It had to be extended to a second day in some parts of the vast country.

About two-thirds of polling stations opened late, while 30% of voting machines did not work, according to an observer group.

Millions of people waited for hours before they were able to vote, while some gave up and went home.

The opposition said the problems were part of a deliberate plan to allow the results to be rigged in favour of Mr Tshisekedi.

Several of the main challengers have called for protests after the results are announced on Sunday.

"We call on our people to take to the streets en masse after the proclamation of the electoral fraud," they said in a joint statement dismissing the "sham" election.
