Kaz, the next BBC Panorama will be one to watch, though maybe not for hard-hat, hi-viz poster boy's fanzone members.
It looks like some of those at the picture party and other events are about to spill the beans on the culture in No10, and why not?
They describe arriving for work the morning after a get-together to find bottles lying around parts of the building, bins overflowing with rubbish and empties left on the table.
They also tell of events with dozens of staff crowded together, and parties going so late that, on occasion, some ended up staying in Downing Street all night.
Mr Johnson attended and made a speech to thank Mr Cain, but as the party developed "there were about 30 people, if not more, in a room. Everyone was stood shoulder to shoulder, some people on each other's laps…one or two people."
These are civil servants so they might be thinking that if some 90,000 or so of them are about to lose their jobs, then why not.
"Do unto others what they would do unto you, but do it first."
