The UK must change its arms export policy to prevent weapons and other military equipment being sold to authoritarian regimes because the Arab spring has shown the system is fundamentally flawed, a Commons report warns...The report of the joint committees on arms export controls includes previously unpublished details about what has been sold abroad over the past two years. It also highlights how an unprecedented number of export licences had to be revoked because of fears that British equipment could be used for human rights abuses in the Middle East and north Africa. In all, 158 arms licences had to be withdrawn.
