I refer the hon. Lady to the letter that the Prime Minister sent to President Juncker on 2 October. The first commitment within that letter was the absolute commitment of this Prime Minister and this Government to the Belfast/Good Friday agreement. We share that commitment not just within the United Kingdom but with our friends in the Irish Government. That is why we have shown flexibility in the arrangements, some of which have caused difficulty to some colleagues in the House, to address the concerns, particularly in the nationalist community, about the possible impact on the Belfast/Good Friday agreement.
