LONDON (AP) — James Murdoch is being recalled for another grilling before Britain's Parliament after former News Corp. executives raised serious doubts about his role in the country's tabloid phone hacking scandal.

The committee of lawmakers investigating the scandal hopes to tie up "one or two loose ends" by recalling the younger Murdoch, committee Chairman John Whittingdale said Tuesday. But the committee said News Corp. chief Rupert Murdoch — who appeared alongside his son at a July 19 U.K. hearing that was televised around the world — was not being recalled.

The two Murdochs gave a dramatic performance earlier this summer, apologizing for a scandal that has shaken Britain's establishment but refusing to accept responsibility for the illegal behavior which happened at newspapers under their watch.

Ex-News Corp. employees have cast doubt on several claims made by the father-and-son media magnates.

Former News of the World tabloid editor Colin Myler and former legal adviser Tom Crone insisted that James Murdoch was wrong when he claimed not to have been aware of a critical piece of evidence suggesting that illegal espionage was far more widespread at the tabloid then was being claimed at the time. more
