Nine British women were facing prostitution charges after being arrested at the weekend for taking part in an oral sex competition in the Greek holiday island of Zakynthos, police said on Monday.

Six British and six Greek men, including two bar owners, were also charged in the incident, which took place at Laganas beach in the south of the Ionian island, which lies off the west coast of mainland Greece, police said.
