FIRST Minister Carwyn Jones is calling for more powers to be devolved to Wales.
Mr Jones has set out the Welsh Government's vision for Wales's long-term constitutional future within devolved UK.
In a submission to the Silk Commission, the UK Government's commission on devolution in Wales, Mr Jones sets out ideas to strengthen accountability and reduce the scope for conflict between the two governments.
The present "conferral" model of devolution means powers are devolved to Wales on specific matters.
Mr Jones instead argues for a "reserved powers" model.
This involves specific areas of responsibility such as constitutional affairs, defence, social security and foreign affairs, which would be "reserved" to the UK Parliament with remaining matters devolved to Wales.
Mr Jones said: "As Wales' First Minister, I am firmly committed to seeking a long-term constitutional settlement for Wales within a devolved United Kingdom. We think it is important to achieve a settlement that is both simpler and clearer than the present arrangements, and one which enables decisions affecting Wales to be taken in Wales. Our submission to the Silk Commission sets out a clear path for this."
The Welsh Government is calling for legislative devolution to be extended in areas such as policing, community safety and crime prevention, water, vulnerable adults and children, public transport, ports, licensing of alcohol and late-night entertainment and taxation.
The Welsh Government believes these responsibilities should be devolved to the Assembly by 2020-21.
It is exploring the scope for extending the devolution settlement in relation to rail services and infrastructure, ahead of this timetable.
It is also calling for the devolution to Wales of executive responsibilities in other areas, with times agreed between the Welsh and UK Governments.
They include large-scale energy generation, the youth justice system and certain marine matters.
Longer term, Mr Jones said, the criminal justice system should be devolved, including the courts, prisons and probation.
The Welsh Government's view is there should be no need for a further referendum before these proposals are given effect.
Mr Jones said: "Where we make proposals for enhanced powers for Wales, we do so with a clear purpose — to enable the devolved institutions to improve the quality of life of people in Wales."
