An inquiry is due to get under way into why hundreds of people were given contaminated blood which led to them becoming infected with HIV and hepatitis C.
Patients in Scotland, including many haemophiliacs, recieved the contaminated blood between 1970 and 1980.
Lord Penrose is to open the inquiry in Edinburgh which will look at how the NHS obtained, treated and issued blood.
He will look at what patients were told, the monitoring that happened and why patients were infected.
In 2003 Rev David Black, 66, and Eileen O’Hara, 72, both died after contracting hepatitis C and their deaths will be highlighted during the inquiry.
The two victims` families started legal action regarding their deaths and an inquiry has been called for for 15 years.
Campaigners were eventually told in April 2008 that an independent inquiry would take place.
Last month in England a similar independently-financed probe, the Archer Inquiry, decided thousands of victims should get extra compensation.
