A man from Sussex who was infected with HIV and Hepatitis C while being treated for a blood disorder is taking part in a protest in front of Bill Clinton.
Protesters want a public inquiry into the use of infected blood products
The man, a haemophiliac, was treated with infected clotting agents in the 1970s when many of the blood products used came from the United States.
The former President was governor of Arkansas, where haemophiliacs say blood was collected from high-risk prisoners.
The Department of Health says the UK government acted in good faith.
The Sussex protester, who does not want to be named, received treatment with Factor 8 which was intended to save his life.
But he was diagnosed with HIV and Hepatitis C at 14.
"I needed Factor 8 because I was in pain, but in being given that treatment I was given a death sentence," he said.
He travelled to Glasgow, where Mr Clinton is addressing 800 business people, to join Wednesday's protest.
Today, blood donors are screened so that blood is no longer taken from high-risk groups such as drug users.
But the affected haemophiliacs are calling for a public inquiry into how they came to be infected.
The Department of Health said: "We are aware that during the 1970s and 80s blood products were sourced from prisoners in the US.
"An ex-gratia payment is available to every person who was alive on 29 August 2003 and whose Hepatitis C infection was due to NHS treatment with blood or blood products received before September 1991.
"The Government of the day acted in good faith, relying on the technology available at that time, and therefore we do not feel a public inquiry would provide any real benefit to those affected."
