Borders, Citizenship and Immigration Bill [HL]

May I ask one question from a position of what I would call chronological ignorance? It is more than 20 years since I was the Minister responsible in another place for Customs, but during that period there were only about 30 ports of entry into this country—or airports at any rate—which were designated international and therefore had a Customs presence. Within the past 10 years, I have landed at a significant airport at which the only Customs presence was a red telephone on the wall which you could call if you wished. Has that changed in the past 10 years so that all airports are now international? If not, will the Bill produce a situation whereby all airports become international, with a Customs presence, because everyone will be interchangeable?
