Join us as we visit the London embassies of key states to discuss the progress of the Nuclear Weapons Ban Treaty. Meet at 11am at Dick Sheppard Chapel, St Martin-in-the-Fields, London for a short service before the walk. We will have briefings and lunch in the cafe after 11.30am and the first embassy visits will be after 1pm. If you are planning on coming it's a good idea to let us know 020 7700 4200, as some (but not all) embassies will require visitors' names in advance.
