David Cameron gets heckled every day of his life. The media never bother to report the names of the hecklers or the gist of what they say.
Yet a single heckler shouts at Jeremy Corbyn at Gay Pride, and not only is that front page news in the Guardian, it is on BBC, ITN and Sky News.
What makes a single individual heckling a politician newsworthy? There are dozens such examples every single day that are not newsworthy.
The answer is simple. Normally the hecklers are promoting an anti-establishment view, so it does not get reported. Whereas this heckler was promoting the number one priority of the establishment and mainstream media, to get rid of Jeremy Corbyn. So this heckler, uniquely, is front page news and his words are repeated at great length in the Guardian and throughout the broadcast media.
