DRONE manufacturers spent hundreds of thousands of pounds to lobby world leaders at last week’s Nato Summit, human rights activists revealed yesterday.

According to research by legal charity Reprieve, arms groups such as General Dynamics and Lockheed Martin paid up to £300,000 to show their wares at the Newport conference. 

“The illegal use of drones to carry out secret bombings is one of the most controversial issues around,” said Reprieve legal director Kat Craig.
