The Scottish Lib Dems are set to push for resignations if the timetable for the completion of two delayed and over-budget ferries is missed again.
Kate Forbes told MSPs last month that the Glen Sannox and as yet unnamed hull 802 will be delayed until at least next year – five years later than planned.
An estimate also put the cost of the final project as high as £240m, almost two-and-a-half times higher than the original £97m.
