Sitting Liberal Democrat member Simon Hughes said in his opening statement that affordable housing was the biggest issue.

Mr Abrams, who works for a housing association, said that he would scrap the right to buy.
In condemning cuts he warned: "Labour cuts your legs off slightly slower than Tories."
Independent candidate Lucy Hall, standing on a direct democracy programme and speaking from the audience, proposed that voters should be able to vote on every bill during the course of a parliament by using an app.
