8.30am - Police reveal more information about the circumstances of April's disappearance. The force said: "Her abduction took place around 7pm in the Bryn Y Gog estate in Machynlleth. It was witnessed by another young child when April was seen getting into a grey or light-coloured van, or van-sized vehicle.
"At the time of her disappearance, April was wearing a purple knee-length coat with grey fur around the hood, her school white polo top and black trousers."

11.40am - Speaking at the Labour Party conference in Manchester, shadow Welsh secretary Owen Smith said: "I am sure I speak for everyone here today and everyone in Wales in saying that our thoughts and our prayers are with April Jones and her family in Machynlleth - the little girl who has gone missing.
"We all hope and pray that she is back in her community and with her family as soon as is humanly possible."
