sir brian langstaff spoke of the evidence he has already read, there have been many, many hundreds oft have been submitted to this enquiry. he said some of the evidence will be harrowing, he found it incredibly moving, and sometimes even chilling. he described it as an active bravery that people had come to give evidence here and said inevitably for some people it would stir up very distressing memories. he promised, though, the victims would have a swift and enquiry as was possible in order to be thorough. we expect the enquiry to last about two yea rs. thank you very much. let's listen to derek martindale, whose blood was infected. he's the first witness speaking at the inquiry. he is speaking. he is not speaking right now, but we expect to hear from him at any moment. let's listen in and see what is happening now. that looks like a record of blood transfusions discussed. and here we have a 1984. receiving different types of blood products, nhs eight and then arm eight. and then if we go to the next page. this should come up another extract from your records, derek. next page. thank
