There is a huge plume of smoke rising from Stratford, east of the City. Nothing on the news as to the origin of this. Mobile networks are already becoming overloaded.
UPDATE: Spectacular plumes, but terror motive “discounted”. Any jokes about London’s taxes going up in smoke can be made in the comments.

MONDAY 12 NOVEMBER
Incident – Waterden Road
Eight fire engines and around 40 firefighters are currently attending an incident on Waterden Road, East London. The Brigade was called at 1206.
Nice view of the plumes of smoke from our office in Chiswick…
It is the Olympic Site. Perhaps the costs are becoming too much and they want out?

Nah, they just want an excuse to push the price of the Olympics up even further.
Quicker than compulsary purchase for those last recalcitrant businesses…
That is your taxes going up in smoke at the Olympic site. Fitting, really.
Now that’s a conspiracy theory I can buy into.
