Clearly Boris is more interested in what his institute of ideas (hard right/ex RCP (!)) influenced advisors tell him to do, than what is in the interests of london or in challenging racism. To be honest i'm surprised how many people are defending this daft decision on here!
i predict boris's fun loving image will soon evaporate and he will be revealed as being actually very anti-party/anti-fun/anti-youth. I think he hopes this festival will wither away or be replaced by some soulless corporate rubbish, and that the few remaining community festivals will suffer too (stoke fest a couple of weeks ago was terribly badly policed and i'm sure it was boris's fault!).
ken, for all his faults, knew that londoners needed and deserved some good free parties and events, and made them happen, which was key to his popularity, in my view. just as we all remember the good old GLC thamesdays from the 80s, especially the last firework extravangaza!
those that are slagging these events for being overly white and/or middle class, lecturing or dull or earnest have, i suspect, mostly not been to them. i went to the rise festival ever since it started about 15 years ago, it was one of the best things in london, and also reached a genuinely diverse (age/race/class) audience - much more so than any other large scale event i've been to in London or anywhere else.
as for those saying that partying under a proper political banner of anti-racism is somehow pointless/not for the likes of us/counter-productive - i think you need to lighten up a bit!
ok, festivals in themselves might not change the world, but what was that emma goldman said about not wanting to be part of a revolution which didn't have any dancing?!
