There is a video circulating on social media, showing what seems to be an alleged evidence of vote rigging.
The video, posted by Andrew Kumi, a candidate for North Waghi, shows a group of men allegedly filling out ballot papers and placing them in ballot boxes for the North Waghi Electorate.
It has been claimed that these men are supporters for incumbent MP Dr Fabian Pok.
