The Guardian reports that top executives at News Corp. -- including Rupert Murdoch and his son, James -- were made aware of phone hacking at the News of the World newspaper.
In a letter written more than four years ago, a News of the World writer who covered Britain's monarchy said that regular conversations were had about phone hacking.
The Wall Street Journal -- owned by News Corp. -- notes that the letter will lead to a new parliamentary hearing that almost certainly will require at least one of the Murdochs to appear.
The committee indicated Tuesday that the written evidence would now lead to a new round of hearings examining the matter.
It said in a statement that it would call a host of new witnesses for oral testimony on Sept. 6.The Telegraph adds that the Labour Party is especially interested in clarification and amplification on these issues.
