Andy Burnham: Traditional Labour areas have changed, we need funding to support areas affected by migration.
Yvette Cooper: We have to challenge the myth UKIP only takes votes from the Conservatives.
Jeremy Corbyn agrees - "you can't out-UKIP UKIP."
Liz Kendall: "We need firm rules on immigration, but we must never try to out-UKIP UKIP. I hated those immigration mugs."
Next question comes from Cardiff councillor Ali Ahmed who wants to know what the candidates would do to deal with UKIP.

Funding for Wales comes up early #labourhustings. Yvette Cooper line that Tories nationalise decisions and localise blame goes down well.
Jeremy Corbyn: I want a constitutional convention. Yvette Cooper: We've got to get a fairer deal for Wales.
Andy Burnham: We have to stop taking people for granted. Liz Kendall: We have to keep fighting for every vote.
Question 2: What reward would you give loyal Welsh support?
Liz Kendall: Eurozone countries should bust every sinew to reach a deal.
Jeremy Corbyn: Greece should be allowed to go down its chosen road.
Yvette Cooper says Britain mustn't turn its back on Greece. Andy Burnham says Greek people should vote yes to the bailout terms that the Syriza government wants to reject.
First question for candidates: If you were living in Greece which way would you vote in today's referendum and why?
Alan Edmunds, editor of the Western Mail, welcomes the candidates on stage.
