Energy, chaos and anger fuelled one fast march today. Starting suddenly from Trafalgar Square with a Whitehall sprint a few thousand annoyingly fit students reversed, ran through the park and headed off towards St James leaving a trail of puffing photographers and red faced cops.
Then they sped up, Vauxhall Bridge Road, back to Westminster, Piccadilly, Regent Street, Oxford Street, Holborn, Aldwych, a few futile attempts by police to block the way were simply ignored. Then St Pauls, Barbican and back to Trafalgar Square. Quite a workout.
The sense of betrayal over the LibDems broken promises is getting stronger, not diffusing. Perhaps the Christmas break will let the pressure drop but there's still a couple of weeks to go and I wouldn't bet on it.
