Uncertainty surrounds the future of a fertiliser plant on Teesside as a Government deal to support production comes to an end.
Around 300 people are employed at the CF Industries plant in Billingham, where production was halted last year when rising energy costs made its operation unviable.
The Government stepped in to help the company, which also has a site in Cheshire, as a side product of CF’s operations is the production of CO2 that is vital for the food industry.
