Lachlan Murdoch will become the boss of one of the world's most powerful media empires. His father, Rupert, has said his eldest son will succeed him as chairman of Fox and News Corp. Lachlan's appointment ends years of speculation over which one of the siblings will take control of the businesses their father built.

At one point Lachlan's younger brother James was favourite for the top job but it didn't go his way. So, who is Lachlan Murdoch, how did he win his father's approval and what impact will he make? Timandra Harkness pieces together what we know about him through interviews he's given and by speaking to people who've worked for and observed the Murdochs.
