John David Cash CBE (3 April 1936 – 8 December 2020)[1] was president of the Royal College of Physicians of Edinburgh.

[3][4] The review resulted in the sacking of Sir Colin Walker as the then head of the National Blood Authority,[5] shortly after chief executive John Adey was also fired.

[6] Cash gave evidence to the Penrose Inquiry[7] and has been outspoken about Britain's tainted blood scandal in which thousands of haemophiliacs died.

[citation needed] Cash was critical of the Inquiry's Final Report, he said it had failed to get to the truth and allowed the responsible executives to avoid giving evidence.

[8] In May 2017 he appeared in BBC Panorama's "Contaminated Blood: The Search for the Truth", stating "If you look at the difference in England and Scotland in terms of the outcomes, you have to conclude that it was not unavoidable, it was avoidable".
