The SOCPA (Serious Organised Crime and Police Act 2005) law means that it is illegal to demonstrate within one kilometer of Westminster without a permit. However, the law doesn’t actually state what constitutes a demonstration so I went to Westminster and stood outside Downing Street (without a permit) in an attempt to find out…

The Policeman at the gates told me that the only way to find out if I needed a permit would be to arrest me and let the courts decide. I didn’t want to push my luck and end up with an ASBO so I left it at this.
Fortunately I wasn’t arrested but I did have my photo taken by lots of tourists.
I still don’t know what a demonstration is and the Police don’t seem to know either, but I think it helps if you’re a girl.
