Welsh Economy

Central to the debate on Welsh Independence is of course  the Economy, or rather the state of the economy  at the time of Independence. Now personally I think there are equally important issues which influence my desire for freedom from the British Empire. Freedom, the desire to have my identity recognised, the right to have control over my Countries affairs etc but of course the Economy of Wales is central to this debate. Trouble is the UK government stubbornly refuses to publish the figures it has available. People have a stab at the figures of course, Gerry Holtham came up with a figure of £6 Billion deficit whilst the UK deficit for the same year was £68 Billion. Given the mismanagement of the Welsh economy by the powers that be at Westminster its hardly surprising to see such a deficit.
Even so I still cannot understand why the UK government doesn't publish the figures in the absence of any cogent rationale critique in favour of the Union. All I see to back up the status quo is fear of change. Of course you can't exactly argue that Wales within the present union is an outstanding success. As Westminster control all of the levers of power, Taxation, Borrowing and Macro/Micro economic policy, they and only they are responsible for the state of the Welsh economy, so maybe that is why they wont publish. Either way the UK government should make those figures public to enable a proper debate, sooner rather than later!
