The House will be aware that we have made commitments to avoid a hard border on the island of Ireland. The hon. Lady makes a very important point that the Irish Government must uphold their promises, too. We cannot have cherry-picking of important international agreements. The Secretary of State is seeking urgent clarification that there will be no disruption or police checkpoints at or near the border. I can confirm that the United Kingdom has no legal obligation to accept returns of illegal migrants from Ireland. It is no surprise that our robust approach to illegal migration is providing a deterrent, but the answer is not to send police to villages in Donegal but to work with us in partnership to strengthen our external borders all around the common travel area that we share.
