"This is what we are now saying to journalists who ask about this:

“The Put People First march for jobs, justice and climate brings together more than 150 groups committed to making the event a peaceful and law-abiding call on the G20 governments to commit to policies that will deliver jobs, end poverty and move to a low-carbon economy.

The event has been organised in full co-operation with the police and the Hyde Park authorities.

We have no evidence that anyone attending intends to disrupt our plans, break the law or commit any acts of violence. Nor have the police informed us that they have any such intelligence.

Put People First is not organising or collectively supporting any other demonstrations or protest events being held in the subsequent week to co-incide with the G20 summit.”
