The independents have 50%. I see Mr. Blevings and Mr. Cronin here. I know Mr. McSorley referred to a margin of 5%. What is the margin on diesel and petrol? Why is there a differential between petrol and diesel? In my survey in Limerick, I found that it varied from 11 cent per litre to no difference at all in price. What margins are companies making on petrol and diesel? Why is there a disparity at petrol pumps in the margins they make? Do they have any problems with supply from oil wholesalers?
