Team GB are hoping to add to their medal haul at the Olympics.

After wins in the women's boxing, dressage and Taekwondo, Britain has 25 golds...and today we could get more in the women's 470 class sailing with Dorset's Saskia Clarke and Hannah Mills.

They're guaranteed a medal and Clark says they're a duo built on an equal footing.
