A leading defence contractor fears jobs will go in a number of sites due to defence spending cuts, which are set to be 8% of the overall budget. In a document seen by the BBC, BAE Systems is worried about the government's commitment to the Joint Strike Fighter project. The aft fuselage for every plane produced is being built in Lancashire, with 1,000 workers there involved, plus more defence-related contractors based in Manchester and Bolton. There is the threat of premature closure of the site at Woodford, in Greater Manchester with the end of Nimrod production.
