News Corp’s $5bn deal to acquire Dow Jones and its crown jewel, the Wall Street Journal, is not expected to close until December. Yet in the corridors of the publisher’s lower Manhattan headquarters, News Corp and its chief executive, Rupert Murdoch, are already making their presence felt.

The television in the lobby, once regularly tuned to cable business network CNBC, now features News Corp’s Fox News Channel. Meanwhile, Mr Murdoch himself has become a regular visitor, setting up office in one of the conference rooms.
