Hon Greyling, as we speak, over 60% of our fuel is sourced from Saudi Arabia and Iran. As you know, we have difficulties with Iran. You source crude oil according to the configuration of the refineries that you have. Basra oil is more suited to the refineries in our country at the moment.
We have to continue that work of diversifying. Also, there are plans in the pipeline to construct a new refinery so that we can also treat much heavier oil than Basra oil. Basra oil is the best because it also enables the production of jet fuel very easily. I don't think we have more room to manoeuvre there, because we depend on the quality of the crude oil that we source and Basra oil seems to be the lightest of them all. [Applause.]
