Furthermore, I wonder what will be constituted as a "protest"? Pride, Love Parade and Glastonbury are all noisy and a *bit* political. I'm sure the bill will be very carefully worded to draw a clear and obvious distinction without any loopholes whatsoever, but parliamentary scrutiny does seem to be a bit lacking currently.
I think that's exactly the point the Tory MP was making with his milk protest.
