LONDON (AP) --

James Murdoch is appearing for a second grilling by British parliamentarians investigating the country's phone hacking scandal.

When Murdoch earlier appeared before Parliament in July, he insisted he'd been blind-sided by the scandal which has shaken his father's media empire.

But the 38-year-old News Corp. executive's assurances have since been challenged by former lieutenants, senior lawyers and documentary evidence.

Murdoch is likely to face sharp questions about a damning email which proved that phone hacking at the News of the World tabloid went further than had long been acknowledged.

He is also likely to be quizzed on his company's spying on the
lawyers of phone hacking victims.

One observer said Murdoch was likely to offer some kind of new
apology Thursday.
