The two CalMac ferries being built at Ferguson Marine shipyard in Port Glasgow are "obsolete" and will spew out "poisonous gases", according to the former owner of the site.
Jim McColl took aim at the Scottish Government over its handling of the ferries fiasco during an evidence session of the Public Audit Committee at Holyrood.
McColl and the Scottish National Party administration have clashed since an Audit Scotland report published earlier this year revealing that two new vessels built at the yard will now cost around £250m - more than double their original price - and be around four years late.
