"Top academics involved in sex research have launched an attack on "seriously flawed" research into British brothels.The academics claim that research into prostitution in the UK published last month by the Poppy Project, which is partly funded by the Ministry of Justice, is inaccurate and unethical.The research in the Big Brothel report "exhibits serious flaws in its mode of data collection and analysis," they warn."
