American cable channel HBO have confirmed they are holding talks with Game of Thrones creator George RR Martin about a possible prequel to the popular series.

The writer has previously made it clear he has “thousands of pages” of material on the history of Westeros which could be used for a follow-up to the hugely popular show.

HBO welcomed an average of 25.1 million viewers per episode for the sixth series of the international Emmy-winning production - which was largely filmed in Northern Ireland.

The figure includes terrestrial viewers, digital recordings, HBO On Demand and HBO GO/HBO NOW.

HBO programming director Casey Bloys told Entertainment Weekly the talks have not yet focused in on any specific element of the back-story.

“I would say it’s still kind of preliminary, ongoing talks. There are areas we are exploring but I wouldn’t point to any one and say this is what we’re going to do,” he said.

Asked if he would support calls for the final episodes of the current series to be screened in theatres as well as on television, Mr Bloys said, "I want everything I can get for HBO.”

The show returns next summer for its seventh season.
