Swazi police on Wednesday shot down suggestions that tourists should be allowed to hire prostitutes if they visit the kingdom for the 2010 World Cup in neighbouring South Africa.
Police spokesman Vusi Masuku said police would act against sex workers as long as a 19th century law banning prostitution remains in force.
"Unless the law is amended, the police will follow it to the letter," Masuku said.
Swaziland hopes to benefit from a predicted influx of hundreds of thousands of football fans for the tournament in South Africa in June next year.
A spokesman for the local organising committee, Bongani Dlamini, had earlier told local media that the issue was being looked into.
"During the 2010 World Cup tournament, we are expecting tourists from all walks of life. After we have taken a decision on prostitution, we will then make a statement or even advise the tourists accordingly," Dlamini said.
Dlamini said the committee had to consider that in some countries, sex workers were not outlawed.
"For example, when a tourist who needs the services of a sex worker arrives and finds that prostitution is prohibited, we will advise him accordingly that he has to propose for love to a Swazi girl first and then consent for sex," he was quoted as saying. Masuku said police were aware of the comments but would not act outside the law.
