It was not until 2017, under Theresa May, that an official inquiry into the scandal was set up, following years of campaigning by victims.
The inquiry, chaired by former judge Sir Brian Langstaff, will give its final recommendations on Monday, with the government expected to deliver an official response during the week.
Following advice from the inquiry, in 2022 the government made interim payments of £100,000 each to around 4,000 surviving victims and some bereaved partners.
In April last year, Sir Brian called for a full compensation scheme to be set up immediately, and recommended interim payments should be extended to some of children and parents of those who had died.
Campaigners have been calling for quicker compensation, with estimates that one victim dies every four days.
These include Steve Dymond, who died in 2018 from a hepatitis C infection acquired from a blood product. Alongside his wife Su, he was among hundreds of campaigners who had called for an inquiry to be set up.
