Valfusk under USA-valet 2020? Rapporterade incidenter.

Gabon's opposition says it was cheated of victory, after official results showed a turnout of 99.93% in President Ali Bongo's home region, with 95% of votes in his favour. Elizabeth Blunt has witnessed many elections across Africa, as both a BBC journalist and election observer and looks at six signs of possible election rigging.

Too many voters
Watch the turnout figures ‒ they can be a big giveaway.

You never get a 98% or 99% turnout in an honest election. You just don't.

Voting is compulsory in Gabon, but it is not enforced; even in Australia where it is enforced, where you can vote by post or online and can be fined for not voting, turnout only reaches 90-95%.

The main reason that a full turnout is practically impossible is that electoral registers, even if they are recently compiled, can rarely be 100% up-to-date.
