Six of the original stars of Grey's Anatomy have agreed new deals to remain with the medical drama for a further two seasons.

Deadline.com, which broke the story, says Ellen Pompeo, Patrick Dempsey, Sandra Oh, Justin Chambers, James Pickens Jr and Chandra Wilson will all return.

The actors' futures on the show had appeared uncertain amid contract negotiations, with series creator Shonda Rhimes writing the upcoming finale of the current season in such a way that their characters could depart.
