Others have raised worries that details of their confidential sources may have been passed to police.
After insisting that wrongdoing had been confined to a single reporter jailed in 2007, News Corp. appointed a management and standards committee last summer to investigate the extent of malpractice at its British newspaper subsidiary. The committee, which reports to News Corp. executive vice president Joel Klein, is scrutinizing several million old emails and other documents.
Murdoch said the committee had been instructed to cooperate with the police. "We will turn over every piece of evidence we find — not just because we are obligated to but because it is the right thing to do," he said in his email.
National Union of Journalists General-Secretary Michelle Stanistreet said Murdoch was sending out "mixed messages" to staff and was using the announcement of his new Sunday tabloid in an attempt to quell dissent. Reporters have complained that rank and file staff have not received the same support as senior managers.
Trevor Kavanagh, The Sun's associate editor, told the BBC on Monday that many staff were uneasy about the activities of the management standards committee. He said some executives were "actually boasting that they're sending information to the police."
