The 2 Sisters Food Group said that the factory at Bevan Way, Alpha Business Park is ‘ageing’ which is the reason behind the closure.

Unite’s national officer for the food industry Julia Long said: "Unite can confirm that the Smethwick site will close on 23 June which is very sad news for the workforce.

"Through intensive negotiations we have managed to save about 250 jobs which will be taken up by other 2 Sisters' sites in the West Midlands.

"Unfortunately, this still means that some 300 workers face redundancy.

"However, given the company's business case that this site was ageing and needed drastic modernisation to conform environmentally, we believe that this was the only achievable outcome.

"Unite always has the welfare of its members as the top priority and we are continuing to support them in the days and weeks ahead."
