The former heir apparent to the Murdoch global media empire has quickly dipped his toes back into corporate waters.

Lachlan Murdoch (33), who unexpectedly resigned as deputy chief operating officer of News Corporation at the end of last month to spend more time with his wife and baby son in Australia, has registered a new company down under.

It is not clear what line of business the Sydney-headquartered Illyria will be pursuing, but Murdoch junior, its sole director and company secretary, is barred from a career or investments in the media industry as part of his A$9 million ($6.8m; €3.7m; £5.5m) exit package from the family firm.

The choice of name for Lachlan's new venture is interesting. Illyria, now the middle European country of Albania, was the setting for William Shakespeare's play Twelfth Night, in which a shipwrecked Viola finds herself in a strange land and opts to disguise her identity.
