Jermaine Jackson is trying to clear his brother's name after an explosive documentary accuses Michael Jackson of child sex abuse.
"There is no truth to this documentary", he told Piers Morgan on Good Morning Britain.
"How sure can you be, Jermaine, that Michael was completely innocent?" the host asked.
"Piers, I'm a 1,000 percent sure because Michael was tried by a jury", an emotional Jermaine replied.
