A number of authoritarian regimes including Saudi Arabia, Bahrain, Azerbaijan, Egypt, Qatar and Pakistan have been invited by the U.K. government to send military delegations to the world‘s largest arms fair, according to an FOI request submitted by the Campaign Against Arms Trade (CAAT). The event opened in London on Tuesday and will give delegates the chance to sample the military hardware of over 1,500 companies.

Other countries to be invited by the British government include Oman, Nigeria, Algeria, United Arab Emirates, Angola, Jordan, Morocco, Kazakhstan and Kuwait. A total of 61 countries were invited to send delegations to the exhibition. Russia was not invited however because of sanctions placed on the country by the West following the conflict in Ukraine.
