Ms Anne Stewart:

I do not know if I would say directly with regard to bid-rigging. Any suspicions we have with any tender, be it abnormally low or high, we generally investigate. If we think there was some type of collusion or something that would be a criminal-type irregularity, we always pass that information straight to the relevant authority. Our sourcing teams are informed to do that. If it is just general issues with the bid we think are irregular, such as it being abnormally low or high, as I said, that we tend to investigate ourselves.
