Olympic rowing: GB lightweight sculls pair dominate heat

Great Britain's women's lightweight double sculls pair Katherine Copeland and Sophie Hosking put on an impressive display in their heat to beat world record holders New Zealand.

Copeland and Hosking were beaten by New Zealand and Denmark at their last meeting, but at Eton Dorney the pair showed they were back to their best by beating their rivals with a three-second lead.

The pair will compete in their semi-final on Thursday 2 August, with full coverage on the BBC.
