I thank the hon. Gentleman because he gives me an opportunity once again to record my thanks to the Police Service of Northern Ireland—a brave group of men and women who do so much to keep not just the people of Northern Ireland but the people of the whole of the United Kingdom safe. We have absolutely no intention of erecting infrastructure at or near the border that would require the PSNI to place its officers at risk. Moreover, I want to underline the point that the threat from dissident republicans remains, whatever future relationship we have with the European Union. It is important that we all remain vigilant and support the PSNI in its valuable work against those who would seek to disrupt the peace process.
