Drivers faced severe delays throughout the evening rush hour.

Earlier this month, Parliament's Business and Trade Select Committee called for changes to the way compensation was being delivered, due to the ongoing delays.

The Department of Health and Social Care said it was working to "bring waiting lists under control", adding that the NHS had recently launched an "ADHD taskforce" to help tackle the delays.

She has rejected calls for a new national inquiry, saying victims want to see action on her recommendations and a new inquiry would cause delays.

For SNP politicians there will be hope the arrival of Glen Sannox heralds the end of Scotland's long-running ferries controversy, although reports of new delays for Glen Rosa mean that may be premature.
