The Public Domain, YouGov and Ryan Giggs
YouGov performed a survey of people to find out what proportion knew "the secret" before I mentioned it in the House of Commons.
Of the total sample of 2,442 82% were sure they knew, 14% were sure that they didn't know and 4% didn't know whether they knew or not. Of the 82% 3% got the name wrong, but 79% got the name right.
From the perspective of the "Law of Confidentiality" I would argue, therefore, that the name was already in the public domain.
This really highlights the total absurdity of the situation.
