Now, supermarkets know they're under the spotlight. We've already seen some gestures from the supermarkets, some price roll-backs. We want to make sure, though, that we're addressing the longer-term issues here. Those price roll-backs are for a short period of time. We want to address the underlying structural issues and make sure there is competition in the market, so we will implement a wholesale access regime and develop a regulatory backstop, and if supermarkets don't strike good-faith wholesale deals with their competitors, our regulatory measures will make it happen for them.
