Military laboratory – no proof of Russian origin

According to its own reports, the UK Department of Defense research centre claims to have found no evidence that the nerve agent used in the attack on a Russian ex-double agent was manufactured in Russia.
“We have not identified its exact origin,” Chief Executive Gary Aitkenhead of the government’s Defence Science and Technology Laboratory (DSTL) told Sky News on Tuesday, 3 April. However, the scientists were able to identify it as novichok, a military-grade nerve agent. They provided the scientific information to the government, who have then “used a number of other sources to piece together the conclusions that they have come to.”
