Nicola Sturgeon has insisted she will answer "all and any questions" on the ferry fiasco at a government-owned shipyard.
Opposition MSPs last week called for the First Minister to give evidence to a Holyrood committee on how Ferguson Marine was awarded a contract to build two new ferries for Caledonian MacBrayne.
The yard in Port Glasgow was bought over in 2014 by billionaire industrialist Jim McColl and was handed the ferry work the following year despite concerns raised by civil servants over value for money.
