    243. The third recording was of Mr Rae to Mr Mackenzie. Mr Rae [. . .] said that Dr Serrano spoke very good English although he did note that he wasn't able to say whether he would have understood the nuances of what had been said. Mr Mackenzie declared that he wanted to run the story and then started telling an anecdote to Mr Rae about a person who he knew who had been drink driving. This was cut off part way through the recording.

I accept that Mr Rae did not give evidence before me, even though a witness statement had been taken from him, and I note that the reasons given for not calling him were reasons which existed before the witness statement was taken, however in my judgment that is no reason to ignore the real evidence contained on the tapes which I have heard.

    98. . In this case, I am to place myself in the position of a reader of The Sunday Times (print or online), a serious-minded weekly newspaper, reading lengthy articles prominently positioned in the news section of the paper on a serious topic of evident political and public importance. In the case of the Front Page and Inside Articles, they are articles published under the Insight brand which I as the reader am told result from an undercover investigation in the course of which the key conversation has been recorded. I would expect the article to be largely comprised of factual revelations though I would also expect some indication of the paper's viewpoint on what it had uncovered.

    "My lawyer requested the whole recording from which these extracts were obtained but this has not been given.

    "The whole recording would show the context of the conversation and demonstrate clearly that at no stage did I agree or offer to work for the fictitious company these undercover reporters claimed to be representing, still less did I commit to doing so for a day a month as the article claims.

    Can an organisation record a telephone call without telling me?

    Yes. In our view, individuals should generally expect that an organisation will keep a record of the call. This could be by recording the call itself [. . .]
