An inquiry will be held into the contaminated blood scandal that left at least 2,400 people dead, the prime minister has confirmed.
It will establish the causes of the "appalling injustice" that took place in the 1970s and 1980s.
NHS patients were given blood products that were infected with diseases, such as hepatitis C and HIV.
Families of those who died will be consulted about what form the inquiry should take.
It could be a public Hillsborough-style inquiry or a judge-led statutory inquiry, Prime Minister Theresa May confirmed.
The prime minister's spokesman said: "It is a tragedy that has caused immeasurable hardship and pain for all those affected and a full inquiry to establish the truth of what happened is the right course of action to take.
"It is going to be a wide-ranging inquiry."
The spokesman said the decision to hold an investigation had been prompted by new evidence.
How long until this is mentioned on the platform? Ah we were right, "scientists" were wrong.
But they wont mention the many lives blood has saved.
