Workers from the threatened Peugeot Ryton plant in Coventry will take their campaign to keep the car factory open to a Peugeot dealer in London tomorrow.
The move is the latest stage in the battle which has seen newspaper advertisements taken out urging potential Peugeot buyers to think of England when they buy their car.
The staff have vowed not to give up despite Peugeot's plans to close the operation and move to Slovakia.
An open letter to all Londoners has also been sent urging those who are considering buying a car this summer to "think of how Peugeot-Citroen has treated its workers in the UK so shamefully and let that influence your decision".
Jim O'Boyle, T&G convenor for the plant, said: "We look forward to spreading our message to the rest of the UK that Peugeot workers are not just going to lay down and accept the sacking of 2,300 workers.
"If Peugeot-Citroen believe they can just leave the UK without any consequences for their market share I have a message for them - we are not going away.
"Unless the company sits down and properly engages with the trades unions to discussing our alternative, this campaign will go on.
"We have a lawful right to proper consultation. The company has a moral duty to honour that."
Meanwhile Peugeot workers facing the axe have been urged to begin debt counselling immediately to soften the blow of unemployment on their family finances.
Debt counsellor Alan Armstrong says it is likely that many are already wrestling with debt, even though they have full time jobs.
Enforced redundancy in a region where large scale job losses are a regular occurrence, could be the final straw, says Mr Armstrong, Leamington Spabased regional adviser with EuroDebt.
Mr Armstrong said: "Even before the plant's closure I suspect a lot of people are just managing to live within their means.
"The shutdown may well tip them over the edge."
He extrapolates that the total indebtedness of the Peugeot workforce including mortgages is likely to be a staggering #58 million.
Mr Armstrong warned against so-called "consolidation loans" which are usually secured on the home.
