Tata Steel is to cut 900 jobs in the UK, including 580 jobs at its Port Talbot site in South Wales as part of a restructuring plan.
It will cut 12 steel finishing and processing sites in England and Wales as part of the proposals.
Other areas implicated by the steel manufacturer's job cuts include Yorkshire, the West Midlands and Teesside.
Additionally, shift levels at the Rotherham and Hartlepool operations will be reduced to align with lower production.
The restructuring comes as the company said it is to restart one of two blast furnaces in Port Talbot early next year as part of a £250m investment programme. The hot strip mill at the Llanwen site in South Wales will also be restarted, Tata Steel said today.
"Today's proposals are part of a strategy to transform ourselves into an 'all-weather' steel producer, capable of succeeding in difficult economic conditions," said Karl Kohler, chief executive of Tata Steel’s European operations.
