The Edinburgh Woollen Mill has confirmed a date is set for its site in Langholm to move to Carlisle.
Scottish Secretary and Dumfriesshire MSP David Mundell made the claim on Twitter.
He called on the retailer to recognise the support the community has provided 'over many years'.
A spokesperson for the EWM Group said:
The date of the move will be on or around 30 July 2018.
