Two or three things are worth mentioning. One of the problems in the region has been the non-payment of public health workers. I have had three conversations with the current President of Yemen in which I have urged the Yemeni Government to make finance available to pay the workers whose job is to try to assist those who may be likely to get cholera. I know that some of the aid agencies have stepped into the breach and paid people to do the same, which has been magnificent. However, the United Kingdom has played its part. We have given £27 million to UNICEF to treat children with severe acute malnutrition, provide safe water supplies and critical hygiene items and support mobile health clinics, and £6 million has been specifically allocated to cholera response. We have been supporting the vaccination programme to try to make a difference. Of course access is vital, but we work through partners, and that is the way to help tackle the cholera epidemic.
