After two former News Corp. employees pointed to inaccuracies in the first testimony of James Murdoch, the News International chief admitted he was “mistaken” about payments made to an ostensibly “rogue” reporter who carried out illegal hacking operations.

The backpedaling immediately prompted calls for him to return and testify again — and this time, under oath. That inquiry has officially called James Murdoch back to testify in October, and under different conditions than his first visit to Parliament.

In his next appearance, which Lord Justice Leveson wants televised, Murdoch will be sworn-in and members of Parliament will be able to present evidence, forcing him to respond. Witnesses may also be called, British media reported.

If he’s shown to have lied under oath, charges of perjury could be imposed.
