The parent company of Vauxhall has said discussions over whether to close the Ellesmere Port site are ongoing - describing reports a decision could be due this week as "speculation".

Following that merger, it was revealed that the future of the North West plant was in doubt - largely due to the upcoming ban on new petrol and diesel cars.
Stellantis chief Carlos Tavares told a press conference Governments can "create situations which destroy the business model".
He said: "If we are told that in 2030 internal combustion engines cannot be sold in the 海角视频 - which we respect as a decision from the country - then we are not going to invest in internal combustion engines anymore because that makes no sense.
"That means that we are going to work on other directions, and then we see if there is a business model for the other directions."
