Absolutely right Stripes.
Simon Brodkin (aka the Lee Nelson character) does stand up and has also worked for both Channel Four and the BBC.

Mr Brodkin is said to have gained access to the event with a fully accredited pass.
Just speculating and not saying they're directly responsible, but an (admittedly very quick) internet search makes me think Leanna Smith from Channel Four and/or Lucy Atkinson of the BBC (named in the link below) might be getting a knock at the door in the not too distant future.
