Brecon and Radnor MP Chris Davies has accused a plan to give Wales a vote on UK military interventions as a "cynical attempt to divide the United Kingdom".

Mr Davies was reacting to a motion passed at the Plaid Cymru conference, where delegates passed a change in policy calling for any direct UK military action to require the consent of both Houses of Parliament and the endorsement of the National Assembly for Wales.

Plaid MP Jonathan Edwards told the BBC's Sunday Politics Wales programme last weekend: "When it comes to the aftermath of war, when soldiers return often with severe physical and mental health injuries, it's the Welsh taxpayer that is responsible for paying for the cost of that treatment through our own health service.

"With all that in mind, I think it's more than reasonable to request that no British government should send our young people to war without the endorsement of our own national assembly."

However Chris Davies MP said decisions should be taken in Westminster, and urged the Welsh Government to "stick to its day job" of providing public services.

"Plaid’s calls for Welsh Assembly Members to be given a vote on whether the UK intervenes in military action is another cynical attempt to divide the United Kingdom.

"MPs get to vote on this because we have a British Army that represents the whole of the United Kingdom and not individual nations. The Welsh Governments remit covers Wales and not the UK.

"I believe that there could be a risk to servicemen and servicewomen if we drag out votes to every elected chamber in order to take military action. Where does it stop? Shall we give local councils a vote?

"Our Welsh Members of Parliament are elected by the Welsh people to make such decisions. The Welsh Government should stick to its day job, improving services such as education and healthcare, which have seen their standards slip since devolution in comparison to our friends across the border. "

Powys Plaid Cymru leader Elwyn Vaughan said involving Wales in the decision making would form a check and balance against the "warmongering tendencies" of the UK Government.

"Recent history shows us the inability of Westminster to do the right thing when it comes to such decisions," he said.

"If we learn anything from past mistakes such as the Iraq war it's that having better checks and balances and the input of the devolved nations into the decision making process would counteract the headstrong warmongering tendencies of Westminster politics."
