Peter Lilley: My Lords, up to half of all goods and produce exported across the border from Northern Ireland to the Republic are produced in Northern Ireland, and therefore cannot be validated as to whether they meet EU conditions at the border between GB and Northern Ireland. Should we not remove the border between GB and Northern Ireland and rely on export controls and the SPIRE system, which I used to exercise as the Secretary of State for Trade and Industry, to ensure that goods exported to the European Union meet European standards? That would solve the problem.
Lord Caine: My noble friend, as a former Secretary of State for Trade and Industry, makes a valuable point. He will of course be aware that the Government have proposed, and are currently discussing, a system of green channels and red channels at points of entry, whereby goods that will never leave the United Kingdom will not be subject to the controls that will be placed upon those goods that will enter the single market.
