Thai activist speaks on lese majeste law
Thai activist Sulak Srivaraksa has repeatedly faced royal defamation charges under the country's lese majeste law.
He is now under investigation for citing academic research questioning whether a battle led by a 16th Century king took place.
The social critic speaks to the BBC's South East Asia correspondent Jonathan Head on the increasing use of the law, which penalises anyone who is found guilty of insulting Thailand's revered king and family.
