4,600 jobs are to go at Rolls-Royce over the next two years as part of a major restructuring drive aiming to save £400 million a year.
The company confirmed that 1,000 jobs will be lost at the headquarters in Derby and will happen this year.
In a statement, the company said around 1,500 jobs would be lost by the end of 2018, with more cuts due in 2019 and 2020.
Rolls-Royce said it was seeking to reduce the number of management roles, and that engineering jobs will also be affected.
