Mazher Mahmood is nicknamed the “Fake Sheik” after his signature ruse of pretending to be a rich Gulf businessman to trap celebrities, politicians and suspected criminals.

He said Monday that his stories had to meet rigorous public interest standards, such as exposing criminality.

He also said celebrities were fair game “if they present themselves as wholesome characters and trade on that status” while behaving hypocritically.

The judge-led inquiry was set up after it emerged that the Rupert Murdoch tabloid hacked the phones of public figures and crime victims.
