Attached is a map of Parliament Square marking out the entrances and where public blocks have said they're meeting. Below is all the information that has been posted to Indymedia about the event.

MPs and Lords return from their summer recess on October 9th. We need to ensure they can’t get back inside Parliament to stop them spreading their culture of fear.
Meet Parliament Square - 9th October - 1pm

Events on the day (as seen on Indymedia)
Anti-authoritarian block
"Taking inspiration from others who are taking action on the day London Anti-Authoritarians are calling for an anarchist bloc. We stand against all war and oppression, and see both the domestic war against 'terror', and the international wars against Iraqis and Afghanis, as being led by this government with the complicity of parliament." - 1pm Parliament Square

"A space for MPs to come find rehabilitation after all their years of war destroying, and community suppressing. We will be offering employment advice and support for all those sacked on the day." - 1pm Parliament Square
