Vauxhall workers at Ellesmere port in Cheshire have voted massively in favour of a new pay and conditions deal which clears the way for huge new investment.
Members of the Unite union at the firm's plant backed the package by 94% after voting over the past few days.
It comes ahead of an expected announcement that the plant will build the next generation of the Vauxhall Astra model. The move will create hundreds of new jobs at the site, where a third shift will be added, guaranteeing work for years ahead. There had been speculation earlier this year that the plant could miss out on future investment by Vauxhall's American owners General Motors, threatening heavy job losses.
One worker said: "We have done our bit and accepted the proposals, which will hopefully secure the future of the factory for many years."
Business Secretary Vince Cable, and officials from the Unite union, have been lobbying the car firm for months in a bid to attract new investment. Mr Cable said:
"Huge efforts have been made to try to secure the future of the Vauxhall plant at Ellesmere Port and the Government has played an important role in making the progress we have so far."
