Nine British women who took part in an oral sex competition while on holiday on the Greek island of Zakynthos are facing charges of prostitution.
Six British and six Greek men, including two bar owners, were also charged over the incident, which took place at Laganas beach in the south of the island.
The women had been paid to take part in the competition, which was video recorded and was to be posted on the Internet, police said.
The men were charged with encouraging obscene behaviour.
In recent years, Laganas has established itself as one of Greece’s most popular destinations for twenty-something holidaymakers and is known for its alcohol-fuelled nightlife.
Tour operators say the resort offers “non-stop partying” and “wild entertainment well into the night”.
Around 15m people – a fifth of them British – visit the eastern Mediterranean country each year, drawn by its soaring summer temperatures, clear waters and sandy beaches.
Zakynthos, also known as Zante, is one of the Greek Ionian islands that is most popular with tourists.
