Animal experimentation on the increase at Porton Down
Almost 10,000 animal experiments have been carried at a military research laboratory in Wiltshire.
The number of tests conducted on monkeys and pigs at Porton Down Defence Science and Technology Laboratory has been on the increase since 2009.
Most of these fall into the "substantial severity" category, meaning the experiments may cause significant or prolonged suffering to animals.
The details were disclosed in a series of written answers from junior defence minister Philip Dunne in Parliament.
