We mentioned this briefly yesterday, but it’s such a beautiful image we had to draw your attention to it again. The Olympic site has been undergoing work to make its infrastructure more secure – power lines are now underground, and cyber security is being stepped up – but the most eyecatching development is an adjustment to stop “all of North London’s sewage suddenly shooting on to the Olympics site” at a speed of 40mph, a prospect that Home Office minister Lord West finds “quite exciting I think”. Imagine it: the Cupcake hushed, waiting for the start of the 100m final, when a squishy roar starts up outside… If anyone sees John Cusack on site, panic.
