Hon Speaker, we are not only focusing on African sources. We are also looking at countries such as Saudi Arabia, because the refineries in South Africa also determine what type of crude oil we should source. If the oil is heavy, it will not be cheap to process it here. So, we look at all those options and we are quite confident that we should be able to have security of supply. We will continue to diversify. It is an ongoing process, because, as you know, you cannot rely on one source, because the wells may dry up or something else may happen. So, it is important to always ensure that we have alternatives. Thank you.
