CalMac owner David MacBrayne Ltd lost £4.6m last year despite a rise in the number of passengers using west coast ferry services.

The company, which also owns Argyll Ferries, saw small rises in passenger and vehicle traffic during 2015/16, according to results published on Friday.

Despite also recording an £18m rise in turnover, David MacBrayne posted a loss for the financial year.

The firm said this was partly because of spending on its successful bid for the Clyde and Hebrides Ferry Service contract.

Chairman David McGibbon said: "This has been another hugely successful year for David MacBrayne Ltd.

"It has been particularly satisfying for me personally to be at the helm during such transformational and exciting times for the company - we really are going from strength to strength.

"Among a year of highlights, winning the Clyde and Hebrides Ferry Service contract is the standout experience for me.

"The uncertainty that has surrounded the company since the tender process began has been unsettling for everyone connected to the CalMac family.

"But our bid was recognised as both compelling and innovative in meeting the needs of communities, customers, stakeholders, our partner agencies and the Scottish Government, while offering best value to the taxpayer. In summary, we were simply the best company for the job."
