The New Zealand founder of an international group to battle child prostitution has died after a long illness.
Ronald O'Grady, who was 83, created End Child Prostitution in Asian Tourism (Ecpat) in 1990 after attending a conference that revealed an increasing number of tourists were visiting Asia to have sex with children.
Ecpat has now grown into a global network of 81 organisations in 74 countries, committed to ending the commercial sexual exploitation of children.
The organisation's international executive director, Dorothy Rozga, said Mr O'Grady had shown great courage and leadership in speaking out against the sexual exploitation of children in Asian tourism in the 1990s, when the issue was not yet seen as a crime.
"Ron's passion and commitment will continue to inspire Ecpat's work worldwide."
