Nestlé's plans to close its After Eight and Toffee Crisp factory in Castleford have been dubbed "a body blow" for the town by ­unions.

The factory is facing ­closure in 2012, following a proposal to merge Nestlé's UK seasonal manufacturing into its Halifax site. Castleford currently ­employs 210 people.

Ninety per cent of production would remain in the UK and a small proportion of exports would transfer to Hamburg under the proposals.

"Our aim is to offer our people alternative jobs," said Nestlé Confectionery UK MD David Rennie.
