Salmon farmer Grieg Seafood has said it will divest its assets in Shetland, Scotland, "when the time is right" to focus on operations in Norway and Canada.

The company had previously announced it would be ceasing operations on the Isle of Skye, which come under Shetland's remit, but in its Capital Markets Day presentation released to the Oslo Stock Exchange on Tuesday, it said this will be expanded to include all operations in the region.
