I have read the Good Friday agreement. I read it as the Parliamentary Private Secretary at the Northern Ireland Office, and I have read it as a Minister in my Department. I think that it is absolutely right that we should protect all elements of that agreement. Of course the hon. Gentleman will know that the issue of EU citizens and UK citizens sits alongside the common travel area arrangements and the commitments that we made under the Good Friday agreement, which stand regardless. I am very glad that we have been able to work very effectively with the Irish Government to convince all the other EU member states that those issues should be respected whatever the outcome of the negotiations and whatever the arrangements we reach between the UK and the EU.
