The government has been urged to re-examine a British company’s contract to export hi-tech machinery to Armenia, after the Guardian uncovered links to the supply chain for Russia’s war machine.

Sanctions experts and the chair of the House of Commons business committee questioned the government’s decision to award an export licence to Cygnet Texkimp.

The engineering company makes machines that produce carbon fibre “prepreg”, a lightweight and durable material that can be used in a wide range of civil and military applications.

The machines are understood to be undergoing final assembly at the company’s warehouse in Northwich, Cheshire, and could be just weeks away from being exported to a newly formed company in Armenia called Rydena LLC.

Rydena was established two years into Russia’s invasion of Ukraine by former executives of a company that has emerged as one of the Kremlin’s important military suppliers.
