Taxation exists to pay for public services. It’s very important if we are to have high-quality public services that we have a taxation system that works. It’s not there primarily as a means of economic development; it’s there to get money for services that we all rely on.

The two taxes proposed to be devolved on 1 April 2018 raise limited income. The policy intention is to continue to reduce landfill, and thus landfill disposals tax, by increasing recycling. In fact, the Government would probably consider it a success if landfill tax brought in no money whatsoever. While land transaction tax is highly volatile and cyclical, the amount of tax raised is small enough not to materially affect the Welsh Government’s expenditure. It will, however, be critical to get a fair deal on this tax to ensure no detriment and to set the principles for any future taxation that is devolved.

I agree with Nick Ramsay about the importance of mediation. If I could just mention the money we didn’t get from the London Olympics, the Treasury acted as judge and jury, and we got roughly the same amount of money that I believe we should have got for Swansea, never mind for the whole of Wales.

I am nervous on the devolution of income tax. We know that it fell by £400 million between 2007-08 and 2009-10. Even the biggest critics of the Welsh Government probably wouldn’t blame the Welsh Government for that fall, yet, if income tax were devolved, they would take the hit. Any change to the way that Wales is funded should give protection against reductions caused by actions outside the control of the Welsh Government and the Welsh Assembly. There must be ‘no detriment’ written in there, and not for the short term, but for ever.

I have a question. If you think specifically back to Silk, there was talk about the devolution of the aggregate levy. That’s something that seems to have been on the back burner for a long time. It’s not a particularly large sum of money, but I think it is a tax that is easily, I hope, devolved. Can the Minister give any further information on the devolution of the aggregate levy? And will the Minister commit to make keeping the funding floor the key aspect of any negotiations, so that we have it if the amount of money coming into Wales goes up, or if the money that has been spent goes up, so that it’s not just there when the money is going down, and to ensure that ‘no detriment’ is written into the whole system, so that we don’t lose out? Will the Minister continue to push for some form of mediation; someone to adjudicate between the Welsh Government and the Treasury? I don’t know if I’m allowed to say this, but I don’t trust the Treasury to be fair. [Assembly Members: ‘Oh.]
