I've certainly, personally, consistently made the argument for the Barnett formula to reflect the spending in England and in Wales. In fact, I led a coalition of organisations to have the Holtham commission set up, using this as one of the examples. And when I was director of the Institute of Welsh Affairs, I consistently made the case, so I'll take no lectures from the Member on that. But she is absolutely right that Westminster Governments of different parties have not recognised that Wales deserves more investment, and that's why I repeat my call to the Conservatives for all in this Chamber to come together to see if we can agree a cross-party call to the UK Government to think again on the way Wales is treated when it comes to rail investment.
