Wonder Woman has been dropped as an honorary United Nations ambassador, less than two months after being appointed following outrage over her raunchy image. 

The fictional comic book heroine was chosen to promote women's empowerment and raise awareness around gender-based violence, but the decision was criticised by many.

Some 45,000 people signing a petition against it, saying that Wonder Woman was "not culturally...sensitive" and that they found it "alarming that the United Nations would consider using a character with an overtly sexualised image".

The character was being used as part of a UN and UNICEF year-long campaign for gender equality.

Lynda Carter played Wonder Woman in the TV series

Wonder Woman first came into popular culture in 1941 in a comic book, with Lynda Carter making the role famous in the camp 1970s TV series.

The Amazonian superhero was most recently played by Gal Gadot in Batman v Superman: Dawn of Justice, with a standalone film set for release in June 2017.

DC Entertainment, which publishes DC Comics, said it was pleased with the exposure Wonder Woman had brought to the cause.

Wonder Woman's association with the UN is now set to end on December 16.

A spokesperson for the campaign moved the downplay the controversy, saying it is not uncommon for their use of fictional characters to only last a few months.
