Business Secretary Lord Mandelson is to visit GM's van-making plant in Luton today (3 July) where he is meeting the unions and Vauxhall workers.
As part of those talks he will update them on discussions that the Government has been having with all the parties involved and reiterate the Government's commitment to continued Vauxhall production in the UK.
Lord Mandelson said: "I want workers at both Luton and Ellesmere Port to know that we are doing everything possible to secure a long term commercial future for Vauxhall.
"I and my officials are in constant contact with the US and German governments, GM US and GM Europe and others to ensure Britain's interests are fully represented. We also continue to have detailed discussions with Magna and other interested parties.
"Luton produces the award winning Vauxhall Vivaro van and soon Ellesmere Port will build the new Astra. The Luton plant represents nearly a fifth of the UK light commercial vehicle market. Vauxhall is an excellent and very popular UK brand. Continued Vauxhall production remains a top priority for this government."
