"The merger application is complex and involves a number of markets throughout the fuel supplychain. We have identified and notified Z Energy of several areas that we are continuing toinvestigate. These include storage terminals, aviation fuel, bitumen and the supply of diesel tocustomers who purchase it in bulk or through truck stops. Further work is also required toinvestigate the retail supply of petrol and diesel, as there are a number of retail sites where, if themerger proceeded, few options would remain for consumers.
We are assessing the competition effects of the proposed merger in these markets in consultationwith Z Energy and market participants. "
