Owner of Port Talbot steelworks offers fresh talks as last furnace faces closure

Sources say Tata offer is predicated on unions at south Wales site agreeing to suspend future industrial action

The owner of the Port Talbot steelworks has written to trade unions offering fresh talks amid a battle to delay plans that would see 2,800 jobs lost and production suspended at a site that has been in operation since 1951.

The Guardian understands that a letter sent on Sunday afternoon by Rajesh Nair, the UK boss of Tata Steel, has offered a new round of discussions about future investments at the company's plants in the UK, including Port Talbot.
