Well done Jamie for putting this together after such a long time since it happened. In case anyone's interested I have quite a lot of footage of my own shot on that day. There were exactly 350 people on the march - Andrew Bradstock counted them! Getting into one of the most heavily secured private gated estates in Britain governed by it's own Act of Parliament was a lot of adrenaline and fun.
As the super rich buy bigger and bigger houses as an investment, squatters are squatting bigger and bigger houses in more and more luxury - hurrah!
