The leaders of the world’s most powerful nations will meet in London in April.
They come together against a backdrop of world slump, war and rising anger at the nightmare they have created.
The point of the G20 is meant to be to find solutions – but world leaders are running out of ideas. Gordon Brown will want to present himself as the man with an economic plan.
But he can hardly boast of any successes.
There are no signs either of any serious initiatives on Palestine. And the main debate in terms of the “war on terror” is likely to be over the need to escalate the action in Afghanistan.
Given the massive demonstrations over Gaza and the rage people feel as jobs go and banks are bailed out, there will be very big protests at the G20.
The G20 meeting will also be Barack Obama’s first visit to London and many will want to urge him to push for real change.
On Saturday 28 March the TUC has called a “Put People First” demonstration, demanding jobs, public services and an end to global inequality.
The first anti-war event will be a march in central London on 1 April – the day before the G20 begins and the day Barack Obama visits parliament.
The second will be a protest at the G20 itself. These protests have been called by the Stop the War Coalition, the Palestine Solidarity Campaign, the British Muslim Initiative and CND.
People are already mobilising across the country for the protests.
Many groups are coming down to London and travelling on to the anti-Nato protests in Strasbourg, France, leading up to a mass demonstration and counter conference on 4 and 5 April.
We have the potential for a week of protests our world leaders will never forget.
