A thousand years ago the Vikings used to sail up the Thames and raid London. So how about all dressing up as Vikings and sailing up to the Excel Centre and then rushing into to it shouting Viking war cries and waving ritual swords and spears. It might not shut the event but it will get loads and loads of publicity and raise questions about the event in the press and in Parliament.

During the anti-roads protests there was a man who used to dress up as King Auther and attend anti-roads protests complete with ritual sword and authentic medieval clothing! So maybe dressing up as Britains ancient figures who have come back to join the protest movement is the way to protest and raise to maximum effect!
