A Political Meteorite?

I was very interested to read David Meldings article in today's Western Mail, where he proposes a radical solution to 'federalise' the UK - not as a way of speeding up Welsh and Scottish independence, as opponents to even limited devolution continually claim - but as a way to protect the union, and to prevent its breakup.

Does this mean that the Welsh Conservatives will now actively support a 'Yes' vote in the referendum, or will they now say that we dont need the referendum as it is a moot point as an incoming Conservative government in Westminster will give us a lot more than is currently on offer.

Could this be the political meteorite that will finally wipe out the Welsh Labour dinosaurs??
