UNION officials at Peugeot-Citroen today raised the threat of industrial action to fight the shock closure of the UK factory, with the loss of 2,300 jobs.
French unions are expected to be contacted to seek solidarity support as part of protests against the planned closure of the Ryton factory in Coventry.
Shop stewards from Amicus and the Transport and General Workers' Union were meeting at the factory today to decide how to respond.
There was said to be a mood of anger and defiance among a `poleaxed' workforce.
One union official said the stewards were discussing plans for a ballot on industrial action which could cripple production of Peugeot's 206 model.
He added: "The mood is one of anger and disgust at the way the company has done this and the fact that Ryton is being painted as the most expensive plant in Europe.
"The company has made it the most expensive plant by sourcing all its parts from France. We have a verbal agreement with the French unions that any closure or attack on one plant is an attack against everyone. We will be seeking solidarity action."
Peugeot-Citroen today made it clear it will not change the decision to close Ryton, which the company repeated was the most expensive of its European plants to run.
"We have no choice but to do it," said director of communications John Goodman.
He said each car built at Ryton cost £288 more than at other Peugeot-Citroen factories in Europe.
Mr Goodman added: "The reasoning behind this is based on economics. We import 75% of the parts and export 70% of production."
He admitted there had been productivity improvements at Ryton, but added that the company had faced huge increases in raw material costs, amounting to £243m at Ryton last year.
