London’s day festivals are a key jewel in its summer crown (its flower crown, if you will) and the prospect of getting rid of them, or even relocating them, feels like an unnecessary effort of bitter individuals who chose to live in the centre of a city. Yes, Brockwell Park is not Soho, but it’s still a park in a capital city. And maybe the price of unfettered access to a gorgeous park 348 days of the year is the 17 days for which you have to surrender it to make 30,000 other people very happy.
