Yes, and I think it has been clear from the department that, like any responsible Government or department, we would act if issues arose. The noble Lord mentioned the sheep sector; in the temporary tariff regime we brought forward, we recognised the sensitivity and potential vulnerability of that sector. He is absolutely right: we need to be alive to, and ready to act on, issues of weather or markets. That point is well made.
The noble Lord raised the issue of the euro. Defra and the DAs have agreed to retain references to the euro in retained EU legislation at the point of exit. This is because, at the point of exit, the CAP will be part-way through making payments under current schemes. To minimise disruption and avoid a difference in sums paid to farmers before and after exit, we will retain the euro until an appropriate time when we can make the change to sterling with minimal disruption. We intend to bring forward regulations to amend euro references to sterling later. These regulations will of course be subject to normal parliamentary scrutiny. In addition, we will work with the devolved Administrations on any changes.
The noble Lord, Lord Beith, asked about retention. On implications for farmers, I reiterate that the Government have guaranteed that the current level of agricultural funding under Pillar 1 will be upheld until 2020 as part of the transition to new domestic arrangements, and that all CAP Pillar 2 agreements signed before 31 December 2020 will be fully funded for their lifetimes. The exchange rate for BPS 2018 is already set for the scheme year, meaning that farmers paid either side of exit day will be subject to an identical exchange rate.
The noble Lord, Lord Beith, asked how many state aid rules there will be after exit. The state aid regime will be rolled over by this statutory instrument, as will the whole architecture through the BEIS statutory instrument. We are not making any changes to the current EU regime beyond those required to make these matters operable.
The noble Lord, Lord Grantchester, asked whether the SIs will be necessary if the Agriculture Bill gains Royal Assent before the end of the current implementation period. If the current withdrawal agreement is agreed,
these SIs will still be needed to ensure that the retained EU CAP legislation is operable in a UK context at the end of the implementation period. This will be the case even once the Agriculture Bill has gained Royal Assent. This is because the horizontal framework regulations, as amended by the SIs, will be required while we continue to operate legacy CAP schemes under retained EU law. Likewise, some CMO regulations will remain after the Agriculture Bill comes into force.
The noble Lord asked about the discontinuity in state aid: will DAs have their own rules and do they take effect at exit day or at the end of the implementation period? This is a reserved policy area, but, as with all the SIs I have had to deal with, there has been a close working relationship with the devolved Administrations. BEIS is working on a memorandum of understanding with the DAs, and my noble friend Lord Henley is working on this. If there is any further information I can bring forward from that, I will let your Lordships have a copy.
In a no-deal scenario—
