The Culture, Media and Sport Select Committee is this morning grilling James Murdoch on phone hacking, with Tom Watson taking centre stage once again.

Watson has just engaged in an increasingly testy exchange with with the News International Executive Chairman, in which he dramatically revealed that he had spoken with former News of the World reporter Neville Thurlbeck, of 'For Neville' email infamy, this morning. Murdoch was clearly shocked by the revelation, and paused for a long time before responding.

However, Watson wasn't done yet. He asked an irritated Murdoch whether he knew the term 'Mafia', and if he was aware of a variety of mafioso terms. Watson then proceeded to characterise News International as the mafia, listing the variety of legal charges, such as perjury, facing the company.

He was though just building up to his big finish:

"Mr. Murdoch, you must be the first mafia boss in history who didn't know he was running a criminal enterprise."

Not surprisingly, James Murdoch was very unimpressed with this, and told Watson he was being inappropriate, before looking to committee Chair John Whittigdale to throw in the towel for him. Whittingdale obliged, Watson confirmed he had finished, and the proceeding moved on to questions by Conservative Damian Collins.

The damage has been done though, and Tom Watson has his soundbite.
