The noble Lord raises a very important point. First of all, the Government are utterly committed to supporting the Belfast agreement and all that that stands for. The Government have set out a range of commitments to Northern Ireland, including a strong role for what we all hope will be a restored Northern Ireland Assembly and Northern Ireland Executive. This will mean that the devolved institutions in Northern Ireland will have a strong role, both in any decision to bring the backstop into effect and in its operation if it does come into effect. I repeat that we are committed to upholding the Belfast agreement and will do everything in our power to avoid a hard border between Northern Ireland and Ireland.
