Katie Archibald and Laura Kenny won gold in the women's Madison at the Track Cycling World Cup.
The British duo, who also took gold along with team-mates Neah Evans and Ellie Dickinson in the women's team pursuit, thrilled the London crowd with a dominant victory.
In a final interrupted by a crash eliminating Russia and the United States, Kenny and Archibald looked in control from the off.
A blistering finish from four-time Olympic champion Kenny secured top spot ahead of Australia, with Belgium taking bronze.
Matt Walls also won gold for Britain in the men's omnium.
A strong ride from the 20-year-old from Oldham saw him triumph in a points race in which the lead changed hands several times.
Walls claimed gold with 131 points, with Mexican Ignacio Prado Juarez second on 123 and Italian Elia Viviani third with 114.
Victory completed a full set of medals for Walls after he won bronze in the team pursuit and Madison silver alongside Fred Wright.
