Andy Evans has been at the forefront of the campaign to secure justice for himself and thousands of others - many who have not survived - affected by what’s been called the worst scandal in NHS history. Next week he’ll give evidence at the Infected Blood Inquiry. He's waited a long time. The group he co-founded, Tainted Blood, takes as its motto words from the philosopher Voltaire: “to the living we owe respect, to the dead we owe only the truth”.
