Blackberry has confirmed plans to cut 40% of its global workforce as it attempts to stem major losses that could amount to as much as £621 million.

In a statement on Friday, Blackberry's chief executive Thorsten Heins said: "We are implementing the difficult, but necessary operational changes announced today to address our position in a maturing and more competitive industry, and to drive the company toward profitability."
"Going forward, we plan to refocus our offering on our end-to-end solution of hardware, software and services for enterprises and the productive, professional end user."
