Video footage shows comedian Sacha Baron Cohen hijacking a far-right march in Olympia, Washington state on Saturday evening.

Baron Cohen can be seen on a stage at the 'March for Our Rights 3', organised by a local far-right group known as the Three Percenters.

The Brit, who previously starred in prank films such as Ali G Indahouse, Borat and The Dictator, leads a crowd in a series of racist chants.

Lyrics included: 'Obama, what we gonna do, inject him with the Wuhan flu,' and 'Journalists, what we gonna do, chop them up like the Saudis do.'

The comedian apparently posed as a supporter of the march and offered to hire security, which was then used to escort Baron Cohen away once organisers realised their mistake.

Photos from the scene suggest he may have even secretly returned to the protest in disguise.
