 The trial of the Grammy-winning US singer, R. Kelly, is set to begin at the US Federal Court in New York on Wednesday. The R&B stars accuse of racketeering, sexual abuse and bribery, charges which he has denied. Some of the allegations made against the singer, full name Robert Sylvester Kelly, date back more than two decades. If he is convicted on all counts, he could face 10 years to life in prison. Kelly and members of his entourage are accused of recruiting women and underage girls to engage in illegal sexual activity with the singer. The stories go back to the start of his career in the 1990s, with many centering around alleged predatory pursuit of teenage girls. The 54-year-old is currently facing multiple state and federal charges in the United States, with accusations including sexual assault, abuse of a minor, making innocent images of minors, racketeering and obstruction of justice. He has repeatedly denied any wrongdoing.
