The Grangemouth petrochemical plant, part of Scotland's biggest industrial site, is to be closed.
800 jobs will be lost after the owners' shock decision to call in the liquidators following a bitter dispute over pay and pensions.
Hundreds more jobs are still under threat at the site's oil refinery.
