Powers over policing should be devolved to Wales, the country's First Minister Carwyn Jones has said.

Mr Jones made the call as he unveiled the Welsh Government's vision for the principality within a devolved United Kingdom.

His administration's submission to the Silk Commission, which is looking at the scope of the Welsh Assembly's remit, says devolution needed to be enhanced and restructured through a new Government of Wales Act.

Mr Jones argued that decisions affecting Wales should be made in Wales.

"Policing and criminal justice are the only mainstream public services which are not devolved to Wales," he said.

"That status quo is becoming increasingly hard to justify."
