Please credit: Tackle HIV. The Duke of Sussex has urged Britons to “go and get a test” for HIV as he told former rugby star Gareth Thomas how he feels a responsibility to carry on his mother’s “unfinished” work. Harry and ex-Wales captain Thomas, who are friends, chatted in depth on a 30-minute video call to mark National HIV Testing Week. The duke described himself as “a typical guy” who just wants to “fix things”, and said he feels an “obligation” to try to continue Diana, Princess of Wales’s bid to remove stigma surrounding the illness.
