Ed Sheeran devastated by death of fan he said he would marry

Singer Ed Sheeran says he is devastated by the death of an unwell fan he met and said he would marry.
Sheeran agreed to wed 19-year-old Katie Papworth, who was suffering from an aggressive form of brain cancer, after they met at a recent concert in Glasgow.
She gave Sheeran a ring, but died before the union could be finalised.
