A passenger-only service remains on one of CalMac's busiest routes due to an ongoing fault with a ferry.

MV Isle of Lewis has been unable to carry vehicles on sailings between Stornoway and Ullapool since the end of last week because of a technical problem with the car deck's ventilation service.

CalMac also warned strong winds would cause additional disruption.

A number of sailings on Wednesday and Thursday have already been cancelled, external.

MV Loch Seaforth, the largest ship in the CalMac fleet which normally serves the Ullapool Stornoway route, is in dry dock at Leith.
