Border Control Posts

If he will publish details of the UK Government request to the EU to establish border control posts at Northern Ireland ports. If, as the Prime Minister has claimed, there will be no checks or border controls for British goods entering Northern Ireland, what exactly are the new border posts at Northern Ireland sea ports and airports for exactly?

I will answer the substantive and supplementary questions together and just repeat what I said a few moments ago—there will be no new infrastructure in Northern Ireland for borders.
