DSEi (Defence & Security Equipment International), is one of the world's largest arms fairs. It exists so that arms buyers and sellers can come together, network and make deals, and it takes place every two years in London's Docklands.
DSEi 2013 took place from 9-13 September: Read how it was challenged.
DSEi is organised by Clarion Events and the Government department UK Trade & Investment's Defence & Security Organisation (UKTI DSO). UKTI DSO's support is crucial to the success of DSEi and its continued existence.
DSEi 2013 featured 1,500 exhibitors from around the world, displaying arms ranging from rifles to tanks to fighter jets to battleships. They were joined by "trade visitors" and military delegations, including countries involved in conflict and from human rights abusing regimes, as well as those with desperately underfunded development needs.
It all took place in secret, behind heavily protected security fences and police lines - designed to allow arms dealers to trade their wares unhindered by transparency or public protest - and subsidised by the UK taxpayer.
