STAY IN TOUCH ON THE DAY: Everybody taking action will be updating others on Twitter using #StopDSEi. Add your updates and find out what others are up to as well.

Don't have Twitter? We'll be sending text updates and running a phone-in line with the latest news. Find out how to stay up to date and share your reports here.

ACTION ON THE DAY: From critical mass in the morning to action at the Clarion Defence and Security offices in Earls Court, Bubbles Not Bombs, Sparkles Not Shrapnel, a mass lobby, and creative direct action all day on the DLR trains- there's a full day planned. Check the Stop The Arms Fair website for a full list of call-outs and see what you can get involved in!

We'll be ending the day with a mass-action “Die-In” at the BAE systems offices in Carlton Gardens (SW1Y 5AD ) at 5pm. BAE are the UK's largest arms company - and a “platinum” sponsor of DSEi - the world's largest arms fair.

MEET OTHERS, DE-BRIEF AND SUPPORT: Stop The Arms Fair will have a drop-in space at the Friends Meeting House in Euston (NW1 2BJ ) on Monday 12th and Wednesday 14th, before and after the Day of Action. If you need accommodation, information, bust cards, or a space to de-brief and access support then please drop in and see us.

CHECK THE WEBSITE: There's loads of useful stuff including legal info, maps and travel info, a floor plan of the arms fair, timetable of actions, and logistics for the day of action.

SEE YOU FOR ACTION TO STOP THE ARMS FAIR ON TUESDAY!
