Woolworths CEO Brad Banducci has announced he will retire in September. The announcement follows Mr Banducci walking out of an interview with the ABC's Four Corners program on the supermarket sector, which aired on Monday.

Alan Fels, former Chairman of ACCC says the Four Corners interview showed that "whatever his commercial abilities, he wasn’t so good on dealing with public opinion". He says the supermarket giant faces a "whole stack of public inquiries, and maybe he’s not the best person to deal with those types of problems."
