Brendan Barber warns cuts will cause 'massive damage'
People from across the country are converging on London for a march in protest at the coalition government's spending cuts.
The Trades Union Congress predicts more than 100,000 people will join the march, to be policed by 4,500 police.
Brendan Barber, General Secretary of the TUC warned the cuts were a "smokescreen" for a "massive attack on our public services".
