Workers at a defence facility in Perthshire have staged a silent protest outside the gates.
DARA workers do not want the firm sold to a Canadian company
Employees at the Defence Aviation Repair Agency (DARA) at Almondbank are concerned by plans to sell the business to the Canadian company Vector Aerospace.

More than 200 engineers and technicians are employed at the site.
Local politicians have been backing the workers' protest.
Roseanna Cunningham MSP said: "While the workforce hold their silent protest, it is up to everyone who is concerned for the future of these hugely important Perthshire jobs to speak up and give voice to our support for the workers and their position."
