The Transport and General Workers Union is demanding talks with Delphi Automotive Systems' management after the automotive parts maker announced the closure of the Southampton plant, with the loss of 126 jobs.

The company yesterday announced a major rationalisation of its global operations that will see 11,500 jobs lost and nine plants closed or sold.

It blamed the cuts in a fall in OE business and demand for aftermarket products, particularly in the US. Delphi has forecast that revenues would be $100-$150m below target this year to the end of March.

Colin Lumber, T&G regional industrial organiser, said: "The T&G in Southampton is totally opposed to the closure of the Delphi plant in the city. We will be seeking a meeting with the local management here as a matter of urgency.

"This news has come completely out of the blue and we will want to find out exactly what is planned for our members."
