Thank you very much, hon Greyling. In fact, we do both. We do not rely only on PetroSA or the South African oil companies. As government, we also engage sister governments to ensure that the supply can be secured. We engaged the government of Nigeria. As you know, I hosted the vice president of Nigeria and in that binational discussion we agreed that South Africa would indeed secure supply from Nigeria as well. However, as I indicated earlier, we have to do other things too. For instance, we have to ensure that the refineries are in place to process that kind of crude oil as well. Thank you.
