My hon. Friend is absolutely right. There were some in the EU who wanted to mount a sort of land grab, as it were, and to have a part of Northern Ireland that was forever Brussels. But what we have agreed is a pragmatic approach, which means that the EU, quite rightly, can have people in Northern Ireland so that it can be assured that the UK officials who are carrying out our own sovereign procedures are doing so in a way in which everyone can have confidence. I want again to place on record my thanks to Vice-President Maroš Šefčovič for making sure that it was pragmatic arrangements, rather than symbolism, that won through.
