Nokia has announced plans to form a “broad strategic partnership” with Microsoft.
The deal would see Nokia use the Windows phone operating system for its smartphones, the company said.
Microsoft’s Bing will power Nokia’s search services, while Nokia Maps would be a core part of Microsoft’s mapping services.
Earlier this week Nokia chief executive Stephen Elop sent a memo to staff warning that the company was in crisis.
The new strategy means Nokia’s existing smartphone operating systems will be gradually sidelined.
