Thirteen Scottish firms have been recognised in this year’s Queen’s Awards for Enterprise, including double winner Calnex Solutions of Linlithgow.

Originally known as the Queen’s Awards to Industry, the programme has been running since 1966 and awards today are granted across four categories: international trade; innovation; sustainable development; and promoting opportunity.

A total of 226 organisations across the UK received awards this year, only seven of which won in two different categories. Calnex, which makes telecoms testing equipment used by major companies around the world, has been recognised for its contributions to innovation and international trade.
