Embattled businessman Ben Polis has stepped down as the chief executive of EnergyWatch as the controversy surrounding his racist, sexist and offensive comments on Facebook intensifies.

His resignation comes as yet another energy retailer, TRUenergy, revealed this afternoon that it had suspended its association with the business indefinitely following what it said were ‘‘completely inappropriate’’ comments about Aborigines, Asians, women and Prime Minister Julia Gillard on the 30-year-old’s Facebook page.

TRUenergy was the latest company to cut ties with EnergyWatch, after another key client, Momentum Energy — owned by Hydro Tasmania - terminated its relationship this afternoon. The Melbourne Football Club severed ties with the company this morning.

‘‘Clearly, the comments are so far outside of the expectations of our club — and our game — and the context of the players who play for our club the club had no choice but to make the decision,’’ Melbourne Demons CEO Cameron Schwab said.
