Aug 10 (Reuters) - Australia's antitrust regulator said on Thursday it was concerned BP Plc's BP.L plan to buy the petrol stations of grocery giant Woolworths Ltd WOW.AX would hurt competition, a sign it may block the A$1.8 billion ($1.4 billion) deal.
The Australian Competition and Consumer Commission (ACCC) said the buyout would cut the number of major rivals selling petrol, reducing the incentive to keep retail prices low.
"As a result, motorists may end up paying more at the pump," ACCC Chairman Rod Sims said in a statement.
