at our 1430 editorial in the Glass Box, Rupert was talking us through the water story and saying we'd be looking at how for some people the power was going to go off. At that VERY moment, our entire office plunged into darkness. An emergency light stayed on, and all the computers and tellies were on - but all the lights went off and still are.
Here is the first ever footage taken inside a real Glass Box meeting..
1525 UPDATE: JUST as we were discussing moving the show to Westminster in the face of what appeared to be imminent system collapse, the lights came back on. We think we'll be fine. Huddle of bosses over to my left discussing a plan B - which will be decamping to our Millbank office. Trouble is - time is tight. If we don't move now, we're stuffed.
1528 UPDATE: News 24 and BBC World had to combine for a while because of our power crisis. Think we're back.
