CND, Stop the War and many others are gathered in Westminster listening to the revelations of the Chilcot report.
Kate Hudson, CND general secretary, said:
“The report shows that Tony Blair had no respect for cabinet procedure, no respect for Parliament, and no respect for international law.
“A country was destroyed, millions of innocent Iraqis were killed, British soldiers were killed, and terrorism has spread across the Middle East.
“Chilcot reveals the evidence that must now be used to bring Tony Blair to justice. This is our demand.
“Only when justice is served can we prevent disasters like the Iraq war ever happening again.”
