Denial of what, though?
The press conference was an hour long and covered insulin reports, the death of one child in detail, the dismissal of Evans's opinion of one point as "nonsense".
Where does Evans say he hasn't changed his mind?
He can't, because he's on the record as having done so, with the Sun, BBC, Channel 5, and allegedly Private Eye.
Those long words are just that, words.
Where does he deny changing his mind?
