A kit which made female cyclists appear nude has been called "unacceptable" by the head of the sport's world governing body, Brian Cookson.

Colombian team Bogota Humana's outfit had a nude-coloured fabric around their waist and hips.

A photo at the Tour of Tuscany caused controversy on social media and UCI President Cookson says his organisation are "on the case".

"It is unacceptable by any standard of decency," he said.
