Some 10,000 protestors have gathered in London to stage a series of demonstrations before and during the April 2 G-20 summit to be attended by world leaders, including Prime Minister Manmohan Singh, as London Police prepare to combat the "unprecedented" security challenge.
The first of such demonstrations will be held on Saturday. It has been organised by an alliance of more than 150 unions, environment and faith groups under an umbrella calling itself Put People First.
The organisation says: "Our future depends on creating an economy based on fair distribution of wealth, decent jobs for all and a low-carbon future. There can be no going back to business as usual."
On Saturday, the protesters will march four miles from the Victoria Embankment to Speaker's Corner in Hyde Park on a route past the Houses of Parliament, up Whitehall and along Piccadilly, and then culminate in a rally in Hyde Park.
Trades Union Congress general secretary Brendan Barber said: "Never before has such a wide coalition come together with such a clear message for world leaders."
