Ivan Mercer, GMB regional organiser, said they were bitterly disappointed at the news, but felt it was not unexpected.

'We believe this decision has been in the pipeline for at least two years and wasn't just made recently,' he said.

'The company has not consulted meaningfully or transparently in the process and at no stage has it looked to avoid having to take this decision.'

He said the union had made various proposals to save Britvic money but the company had never indicated it was looking at anything other than closure.

'We are disheartened by the manner in which Britvic has gone about this - it has been a sham consultation.'

He said the union had 150 members working at the company and 250 across both sites, including Unilever.

'Unilever has behaved in a completely different manner and I do believe the company is committed to remaining in Norwich but this announcement sounds the death knell for them,' said Mr Mercer.

'If they do stay it will not be at the current site.'

A number of Britvic employees approached for comment while leaving the plant on Friday said they were not allowed to speak to the media.

One employee, who declined to be named, described the mood as 'ugly' following the announcement.

'Everyone is really p***** off. The mood is really bad in there.

'You don't want to know the kind of language that's being used. It's ugly'
