Mark Watts is the Editor-in-Chief of the investigative website Exaro. He is a journalist, author and television presenter, as well as being the co-founder of the FOIA Centre, which specialises in research using ‘open-access’ laws, such as the Freedom of Information Act.

Mark ran the investigations unit at Sunday Business, and has worked as a reporter on several national newspapers, including The Sunday Times, The Independent on Sunday, The Sunday Telegraph, and Sunday Express. He also worked on Grenada Television's World in Action and other current-affairs television programmes. Mark’s book, The Fleet Street Sewer Rat, published in 2005, exposed some of the ‘dark arts’ of British newspapers years before the phone-hacking scandal brought down the News of the World.
