Established in October 2011, the Silk Commission has examined the shape of devolution in Wales.

Having made the case for the Assembly to have some tax raising powers, it has now received evidence from figures across Wales on whether its current powers need to be reveiwed.

Many Welsh political figures, including the first minister Carwyn Jones and the Welsh Conservatives, have called for the Assembly's powers to be enhanced.

But through the Silk process some dissenting voices on devolution have emerged from Gwent.

Monmouth MP David Davies, known for his cynicism towards devolution, told the Silk Commission that further powers would be "another step along the slippery slope towards independence."

"Regular calls for more powers for Wales, when English MPs cannot vote on Welsh affairs, but Welsh Members can vote on issues affecting only England will inevitably lead to a call for an English Parliament," he wrote.

"If this trend continues it seems likely pressure for independence for Wales may well come from England at some point in the future."

Mr Davies claimed that Wales being able to borrow has the potential "to become a mirror image of the catastrophe being played out on our televisions screens each evening", with one part of a shared currency area able to borrow cash without the means to pay it back.

"The only difference is that Wales will be playing Greece to London's Berlin," he said.

However Mr Davies' views differ from those of his own party at the Assembly.

The Welsh Conservative Group in the Assembly told the Silk Commission that a series of further powers should be devolved to complement the existing system and ensure Wales reaps maximum possible benefits.

"Elements of the present settlement are untidy and we believe the devolution of certain further powers would yield a more efficient and effective system, whilst enhancing the Assembly's scope for improving the lives of the people of Wales."

The group called for the Assembly to have more powers on energy, broadcasting and public holidays.

Rosemary Butler, AM for Newport West, told the Silk Commission that the number of Assembly members should be increased from 60 to 80.

She said that the expectations on AMs, with 44 sitting on committees that scrutinise the work of the Welsh Government and legislation, makes the case for more members than ever.

Mrs Butler also called for the areas that the Assembly can make laws on to be more clearly defined, allowing the Assembly to legislate with confidence in the areas devolved to it.

Her calls stand in great contrast to the anti-devolution group True Wales, which is backed by a number of Gwent faces including Caerphilly borough councillors Nigel Dix, from Labour, and independent David Rees.

In True Wales' submission the group, which campaigned for a No vote in the 2011 referendum on further powers for the Assembly, said the record of devolution means there needs to be a "period of serious and sober consolidation in Cardiff Bay."

Infact the group calls for the process to be reversed ÐÊwith health services passed back to the UK Parliament.

"We in True Wales support putting the 'national' back into Aneurin Bevan's NHS. All British citizens should recieve equal treatment wherever they live," the submission reads "We do not consider the current addiction to limitless power to be conducive either to prosperity or political stability in Wales," the group adds.

"Most politicians argued that voting Yes would turn law-making into a shield against the economic adversity hitting our country.

"So far, the lack of economic and educational dividend since the referendum demonstrates the hollowness of this argument."

It claimed that the historic influence that Welsh MPs had in Westminister is now on the wain.

"If the Silk Commission recommends that the Welsh Government's demands for the devolution of policing and criminal justice be accepted without a further referendum... a dark shadow will forever hover over the legitimacy of its power."

True Wales refused to apply for official No campaign status in 2011. The No camp lost, polling 36.5 per cent of the vote compared to 63.5 per cent for Yes.

The Silk Commission plans to publish its findings in the Spring of 2014
