An Uninvited Guest
The UK arms industry‘s Annual Dinner took place on 3rd February 2015 at the London Hilton on Park Lane. The £246-a-head banquet was attended by arms industry executives and more than 40 MPs.
This industry, which profits from selling arms to repressive regimes and conflict zones including Saudi Arabia, Israel and Bahrain, is supported and subsidised by the UK government.
Activists from Campaign Against Arms Trade were there to greet the arriving arms dealers and deliver an impromptu speech asking them to reconsider their choice of career.
