ALINTA chief executive Bob Browning and chairman John Poynton last week yielded to public criticism of their involvement in a proposed management buyout of the energy utility by resigning from their respective positions. Mr Browning stepped down last Thursday, with his colleague Mr Poynton resigning from the board the following day, having already abdicated the role of chairman at the time of the MBO announcement. Mr Poynton has been replaced by former Woodside chief John Akehurst, while Mr Browning’s services would be retained by Alinta until June 30, with Alinta’s asset management chief operating officer Peter Magarry taking up the position of acting chief executive.
