SNP ministers are under pressure to call in police following a bombshell documentary over possible preferential treatment in the awarding of a contract for two over-budget and late ferries.
Deputy First Minister John Swinney has called in Audit Scotland to look into the ferry fiasco after the BBC reported Ferguson Marine, the Port Glasgow shipyard that won the contract to build the ferries for the CalMac fleet, was given sight of a more than 400-page document setting out the technical requirements for the vessels.
The reports say a design consultant passed the document to the yard. The shipyard was also allowed to change its design during the tendering process, making its pitch almost £10 million cheaper.
