Don’t know much about this, but keep getting tipped off from different directions. Doesn’t sound like the usual rent-a-crowd of Trots. A disorganised flash mob, no speeches, just show up on the steps of the Bank of England…

UPDATE 17.50 : From the comments, going around the City:

To all staff in the London Office

We have been informed by the City of London Police that a protest against financial institutions in the City will be taking place from about 3.00 pm till 6.00pm tomorrow. The protest by the ‘Socialist Workers Party’ will originate in the area of Bank Junction and the Royal Exchange. Exact numbers of demonstrators are not known but the Police will be in attendance as normal.

We will be increasing building security arrangements as a precaution. Your safety is our priority and the advice we have received is for staff to use caution and remain vigilant when travelling through the City.

Thank you for your co-operation.
