The UK plans to expand its probe into 21st Century Fox’s bid for broadcaster Sky, exposing Rupert Murdoch and his family to further scrutiny over governance at their media empire and adding to the uncertainty about the £11.7bn (€12.8bn) deal.

Rupert Murdoch has brought his son Lachlan back into the fold at his global media empire by appointing him co-chairman of News Corp and 21st Century Fox after seven years away.

Lachlan Murdoch resigned today as an executive at his billionaire father Rupert Murdoch’s News Corp.
