No War, No Trident and No News (London anti-war protest, April 10th)

Londoners are protesting again! (In case you don't know, there are protests in this city almost every day). Well, on April 10th it was a 'No War' and 'Stop Trident' protest in which the usual suspects participated (see photo for example). However, I found nothing about this on BBC. Nothing! Would you consider this a case of mass media neglect or the general politics of the country?
