Cameron and Jones in row over further devolution in Wales

David Cameron should delay further devolution until the Welsh and UK governments can agree a deal that will "stand the test of time", the first minister has said.

The prime minister had accused Carwyn Jones of "playing politics" by claiming the UK government's plans could reduce the assembly's powers.

The UK government is due to publish draft plans to change the way devolution works in an attempt to set out more clearly who runs what.

BBC Wales' Westminster correspondent David Cornock explains.
