Extract from security update from MPS just issued to businesses in the City:
"The largest protest march yet is planned for 20 November, when at least 60,000 protesters are expected to march through London. The demonstration is planned to start in the Bloomsbury area at about 1200hrs with members assembling at Mallet St. The demonstration itself will start at 1400hrs when they will move to Russell Square, Southampton Row, going along Kingsway, round the Aldwych, Southbound over Waterloo Bridge, past Waterloo Station, down York Road, north over Westminster Bridge, along Whitehall and into Parliament Square, up to Trafalgar Square where it will finish at 1900hrs.
Due to the large numbers involved, the police anticipate that there will be a need to close not only the roads mentioned above, but also the areas north and south of the River Thames"
