Veteran left-wing MP Jeremy Corbyn received the warmest welcome of all the candidates at a Labour leadership campaign hustings.

Labour leadership frontrunner Andy Burnham has used a speech to focus his campaign on apprenticeships and technical education.
He said: "I believe we need a revolution in technical education, giving it all the support and prestige that comes with the university route. And that means access to financial support too."
"My ambition is for a national Ucas-style system for apprenticeships, raising sights, rewarding those who work hardest, giving all children hope and a goal in life."
Mr Burnham indicated that he would back changes to the tuition fees system for university students, which he said burdens young people with too much debt.
