This week on the Big Picture, we speak with British political activist, author and deputy chair of the Stop The War Coalition, Chris Nineham.

Nineham was instrumental in organising the historic anti-war demonstrations in 2003 against the invasion of Iraq - which saw millions flood the streets in major cities across the globe - and is considered the largest protest in UK history.

Now he's helping bring together another global call to action on January 13 - this time to call for an immediate ceasefire in Gaza after three months of continuous action.

We speak with Nineham about what it takes to build a mass movement, bringing together activists, unionists and community groups and turn the momentum of the last three months of action into a worldwide push to end war, injustice and poverty.
