CCHQ staffers are a little worried apparently. Does the NUS, who organised the protest, support this French direction? Time for the tear gas…

UPDATE: Molotov cocktail spotted thrown at CCHQ.

UPDATE II: We didn’t start the fire:

UPDATE III: Invasion of the Tower cleared, police being stoned and bricked as they try to push back the crowd. Well more fun than a lecture eh?

UPDATE IV: Riot police are surrounding LibDem HQ to make sure the same doesn’t happen there. Crowds are gathering at Cowley Street

UPDATE V: Flaring up again and police still not in control. Understand Millbank Tower and 30 Millbank (CCHQ) are in the process of being evacuated.

UPDATE VI: Reports of serious glass and concrete injuries and that medics can not get through. The woeful planning and incitement by the NUS President Aaron Porter is going to make his position very tricky. MI5 have shut down Thames House and the red flag has been raised above CCHQ:

Riot police kitting up…
