The one and only Labour leadership hustings in Wales has a sense of urgency which doesn't exist in many parts of the UK because of the assembly election next year.

They all support devolution and to varying degrees they want Carwyn Jones to have a stronger role in the UK Labour party in the future.
Ultimately, the Welsh members will be looking for the person with the right personality to attract enough voters who aren't party members to become Prime Minister.
It's all part of a summer of soul searching by the Labour party as it tries to establish what went wrong across the UK and in Wales where it lost a number of key seats, and didn't see it coming.
