Watch: McIntosh wins goldpublished at 19:58 British Summer Time 29 July
Swimming - women's 400m individual medley
Summer McIntosh took silver in the 400m freestyle on Saturday but the 17-year-old now has a gold medal around her neck as she stands on the podium with the Canadian national anthem ringing around the Paris La Defense Arena.
McIntosh was some way off her own world record time but a lack of competition around her possibly played a part as she flew clear for victory.
