A cure for HIV is still some way off - but today's much-publicised breakthrough in London could be crucial.
That is according to the chief executive of the Terrence Higgins Trust, a prominent HIV charity, who was speaking after news that a London man could become the first person to be cured of the disease.
The 44-year-old man was previously HIV positive, but tests have shown the virus has vanished from his blood. He is one of 50 people who are trialing a new treatment for the disease, created by scientists from five UK universities.
In response, Ian Green told Julia Hartley-Brewer: "I think it's very early days, but we really do hope the results will help future studies on the way to finding a cure.
"If there is the prospect that there could be a complete cure for HIV, what a fabulous day that will be."
