I am happy to give the right hon. Gentleman the assurance that we will continue to engage with all parties and communities in Northern Ireland—that is the right way to proceed—particularly with regard to the operation of the brake. That is set out in the Command Paper, and we look forward to discussing it, and how to codify it, with the Executive, the Assembly and the political parties as we move forward. That is something we are very happy to do.
Just so the right hon. Gentleman is clear, the Stormont brake is based on an existing Good Friday agreement mechanism. The petition of concern mechanism is well established in Northern Ireland as a cross-community safeguard, which is why we have chosen it as the appropriate mechanism for this particular purpose. As I say, we will continue to engage with all parties to make sure we get it absolutely right.
