My Lords, unusually, as a former Treasury official, I am generally in favour of greater devolution—the more so when the likes of the noble Lords, Lord Hain and Lord Wigley, and my noble and learned friend Lord Thomas support a proposal. But on this occasion I fear I should advocate a degree of caution.

I speak having been in the Treasury when the Crown Estate in Scotland was devolved. With hindsight, I think that was a mistake, particularly because there is considerable benefit in looking at offshore wind policy at a UK level. Indeed, the then Government missed a trick. They should have followed the example of I think the Wilson Government in the 1960s, who hived off oil sea exploration from the Crown Estate. The then coalition Government should have hived off offshore wind from the Crown Estate, not least because it gives the Royal Family, who no doubt are a deserving cause, a massive windfall, as my noble friend Lord Turnbull pointed out at Second Reading.

Although I very much understand the case that noble Lords have made on both sides of the House, I think this is something that should not be rushed. There may be a case for devolving further powers to Wales, not least because there is a case for giving Wales similar treatment to Scotland. But if the Government are sympathetic to this amendment, I encourage them to spend a bit more time working through whether there are unintended consequences and, in particular, looking through the financial implications. One thing I would not want to see happen is Wales being disadvantaged financially by devolution. This might be the right thing to do for the longer term, but I encourage the Minister to think twice before agreeing to it today.
