Strikes and protests have been staged across the UK in support of a mass walkout by energy workers angry at the use of foreign workers on a Lincolnshire construction project.
A mass meeting at the Lindsey Oil Refinery, which later dispersed, was attended by hundreds as solidarity action broke out across the country:
• Hundreds of workers employed by BP and INEOS at Grangemouth Oil Refinery in central Scotland agreed to walk out at a meeting. INEOS said the site was safe and fully operating.
