Jessica Ennis has opened the athletics action at the Olympic Stadium with a British record.

She's blown the opposition away with an event best time in the 100-metre hurdles - the first of her seven heptathlon events.

And our team captain Dai Greene has just won his 400 metre hurdles heat.

There's hope for more gold in the rowing - when Katherine Grainger and Anna Watkins go in the women's double sculls final this lunchtime.

But our men have just missed out on a medal in the quadruple sculls, finishing 5th.

Later - cyclist Victoria Pendleton looks for Velodrome redemption in the Keirin - following disqualification in the team sprint yesterday ... and Andy Murray takes on Novak Djokovic for a place in the tennis final.
