Unite has hailed BMW Group's decision to invest £250m into its UK plants in Oxford, and Swindon as a "ray of sunshine".
The company announced the cash boost during a visit by Business Secretary Vince Cable this morning.
Tony Burke, Unite assistant general secretary, said: "This major boost in investment is tribute and reward for the dedicated and hard-working workforce at Oxford, Swindon and Hams Hall.
"The British car industry is once again a ray of sunshine in gloomy times for British manufacturing.
"The UK has the potential to be a manufacturing success story, if we had a Government which was prepared to roll its sleeves up and intervene to support employers up and down the UK."
