The Stop the War Coalition has been one of the most important democratic campaigns of modern times.
It has brought hundreds of thousands of people on to the streets time and again. It has organised protests and lobbies in every part of the country, including by military families.
Most of all, it has been shown to be right in opposing more than a decade of disastrous wars – in Afghanistan, Iraq and Libya – while many of its most vociferous critics supported them.
The anti-war movement has been a vital force at the heart of our democracy. Branding it as somehow illegitimate is an attempt to close down democratic debate and campaigning.
