Britain’s Prince Harry and his American fiancee Meghan Markle delighted cheering crowds and greeted hundreds of smiling well-wishers waving British and US flags, chatting and shaking hands with onlookers who braved freezing weather to welcome them. The couple were visiting a charity fair to mark World Aids Day, something particularly symbolic for Harry whose late mother Princess Diana is credited with playing a leading role in breaking down the stigma that was attached to the disease. The event, held by the Terrence Higgins Trust, remembers lives lost to HIV and marks the progress made in fighting it, Reuters reported. Afterwards, the couple were visiting Nottingham Academy to meet headteachers from local schools and hear about the Full Effect programme, an initiative supported by the charity of Harry, his elder brother Prince William and wife Kate, which seeks to deter children from becoming involved in violence. Regarding the visit, the royal family said: "Prince Harry has spent time in Nottingham both publicly and privately since he first met young people there in 2013, when he was exploring issues around youth violence," German News Agency (DPA) reported. "This event will be full of optimism and excitement, and work will be highlighted to break the stigma of HIV in the Midlands region of England," added the Royal Family.
