Not too much news, what you'd expect really. Looks like the TUC, more than the police, are trying to make the march as ineffective as possible.

Top tips to marchers from TUC:
Stagger Arrivals (People will still be at start of march 3 hours after its started)
AVOID feeder marches (they interfere with disabled access apparently)

They've already condemned anything "that would distract" from the message.
