Yes. I wasn't the editor of the paper when the first use of wireless -- surreptitious wireless. It was to expose an antique dealers' ring, and the only way to get the evidence that people who put up their antiques for sale were being defrauded was for the antique dealer whom we knew, in fact he was an antique dealer who was also a correspondent, had a wire, and there was a van outside, and that led to the exposure of this wrongdoing.
I wasn't the editor at the time, but actually I would have approved it if I had been.
The occasion where I did approve, the second and the only instance I can think of, was when the police were trying to find and identify crooks who were selling franchises to people that were completely fraudulent, and the police said to us, "We need to get this information out to alert everybody, to alert everybody to what was going on", and so the franchise crooks, in conversations with the Sunday Times reporter, the business news reporter, were exposed.
In Times Newspapers, there was one other instance in Times Newspapers under the editor William Rees-Mogg in 1967, when the police force was corrupt, very badly corrupt. Bribes were being taken by policemen to suppress various wrongdoing, and the editor of the Times, William Rees-Mogg -- and I agreed with him, by the way -- arranged for a rather -- well, a very surreptitious recording of one of these transactions taking place between a corrupt policeman and a crook, and that led to the complete reform of Scotland Yard, and then Sir Robert came in, Robert Mark came in, and Scotland Yard began rooting out really massive corruption.
So there were three occasions: antique dealers, franchise operations and corrupt policemen in Scotland Yard.
