Diolch, Llywydd. We would also like to place on record our thanks to all staff in the NHS and beyond who are striving to work through this time, and I'd like to thank you, First Minister, for the briefings you are providing. You can be assured of our ongoing support. Also, we send our condolences to the family and friends of the person who has passed due to this virus. 

First Minister, the impact COVID-19 is having on society we are now beginning to see. My colleague Mark Reckless is in self-isolation due to developing symptoms consistent with the disease. So, in the meantime, if you put up with me asking leader's questions, I would be grateful. 

First Minister, we have a small window of opportunity to control the path of this disease that is wreaking havoc around the globe. The best course we can take is to follow the advice of medical experts, and I for one am comforted that the four nations of the UK are working together on our strategy, following the advice of epidemiologists. The advice to stay at home for 14 days if anyone in your household has symptoms is aimed at curbing the spread of this disease, which modelling predicts could be as much as 80 per cent of our population. While I accept that we simply don't have the resources to test everyone, and that widespread testing would divert vital resource away from assisting those at greatest risk, we do have to ensure we maintain testing for essential key workers. First Minister, we can't afford to have hundreds, possibly thousands, of key staff in self-isolation. Will you therefore commit to ensure that priority testing is carried out on family members and staff working in our hospitals, our care homes and our schools? Our prisons also, the police, fire and ambulance services. These people are vital to the functioning of our society, and we can't afford to lose them unless they have a confirmed exposure to SARS-CoV-2.
