Protestors formed a ring around the DESO building.
Mark Thomas talks to Bruce Kent and others surrounding DESO.
The building was surrounded by around 250 protestors.
For more information on the campaign to shut down the DESO see the web site www.calltheshots.org. The demonstration was organised by Campaign Against the Arms Trade and supported by other groups including the Fellowship of Reconciliation, SPEAK, War on Want, CND, the Liberal Democrats, Plaid Cymru and the Green Party.
