"I haven't had a discussion in my memory" Funny way of putting it 
Not if you punctuate it and provide yourself with weasle words that can be interpreted when the brown stuff hits the revolving object.
Try it like this:
"I haven't had a discussion, in my memory, with Mr Barrosso about this.
Which can later be said to have been a lapse of memory as in "Oh that was just a passing remark made, in a larger context, that had slipped my memory, as I said at the time ~ so I wasn't lying, see"
Mandleson has pulled similar stunts before and will no doubt do so again and of course he has the help of piss poor punctuation, deliberate or otherwise, from his friends at the BBC.
