"PEOPLE of the world, rise up on October 15th!"
That's the message from the United for Global Change website, which is now listing more than 800 cities across the globe where people will be taking to the streets and squares on Saturday.
It says: "From America to Asia, from Africa to Europe, people are rising up to claim their rights and demand a true democracy.
"The ruling powers work for the benefit of just a few, ignoring the will of the vast majority and the human and environmental price we all have to pay. This intolerable situation must end.
"United in one voice, we will let politicians, and the financial elites they serve, know it is up to us, the people, to decide our future. We are not goods in the hands of politicians and bankers who do not represent us.
"It’s time for us to unite. It’s time for them to listen."
