The 2003 anti-war marches

What happened?

On 15 February 2003 hundreds of thousands of people marched through London against the planned invasion of Iraq.

A month later the Commons voted to support military action, despite a large rebellion by Labour MPs.

  • The police estimated the London crowd at more than 750,000; organisers put it at up to 2 million.
  • On 18 March 2003 the Commons rejected a rebel amendment saying the case for war was 'not yet established' by 396 votes to 217, and backed the government's motion by 412 to 149.
  • Two ministers, John Denham and Lord Hunt, and three parliamentary private secretaries resigned over the vote.

Why is it politically significant?

The marches show that mass participation outside elections remains possible, especially among people who avoid parties. They also show its limits: the government and a Commons majority went ahead regardless.
