A French right-wing magazine has been criticised across the political spectrum in France for depicting Gabon-born socialist MP, Danièle Obono, as a slave.

The article in Valeurs actuelles accused Africans of colluding in slavery, and had a sketch of Ms Obono with an iron collar around her neck.

Prime Minister Jean Castex said it was a "revolting publication".

The magazine apologised to Ms Obono but denied the article was racist.

Ms Obono is a deputy in the National Assembly for left-wing party France Unbowed, led by Jean-Luc Mélenchon. She represents a Paris constituency.

She tweeted the image with the words "the far right - odious, stupid and cruel".
