Syrian conflict: Key sarin ingredients sold by UK firms

9 July 2014 Last updated at 16:08 BST

Britain sold chemicals and components to Syria that ended up being used in the manufacture of the deadly nerve agent sarin, BBC Newsnight can reveal.

A leaked Foreign Office document says they were supplied in the mid-1980s.

Ministers will confirm within days that UK firms provided the materials and that Syria has admitted they played a role in its chemical weapons programme.

They will say there were no proper regulations at the time, but that tighter rules and controls exist now.

Sarin has been linked to a number of attacks in Syria's bloody three-year conflict.

Newsnight's investigations correspondent Nick Hopkins reports.
