The resignation of Nihal Gupta from the SBS chairmanship yesterday draws a line under one of the more baffling chapters in the Australian government's management of Australia's public broadcasters.

Gupta -- a low-profile businessman and Liberal Party donor who'd been appointed to a string of plum positions, including the board of the Sydney Cricket Ground, during Barry O'Farrell's premiership -- was named chair of SBS 16 months ago. The role had remained unfilled for six months before that, with the Abbott government refusing to extend the term of merchant banker Joe Skrzynski and taking a very long time replacing him.
