THE future of Port Glasgow’s Ferguson Marine shipyard remains uncertain due to inadequate governance, a watchdog has warned.

Scotland’s auditor-general Stephen Boyle made the remarks after investigating the troubled Scottish-government-owned yard following years of controversy that have seen its contract to build two CalMac ferries, the Glen Rosa and Glen Sannox, run six years late.

It is also more than 220 per cent over budget, and left with a £48,000 income tax bill after former chief executive David Tydeman agreed contract changes for a seconded employee without board or remuneration committee approval.
