I shall come on to exactly that point, but let me continue with this question of a hard border across the island of Ireland and the question of crashing out. The reality is that we know as well that there is not simply a threat around terrorism with that hard border, but there is also a massive threat to the economy of Northern Ireland and the movement of goods including agricultural goods and manufactured goods, which is why the business community and the farmers union in Northern Ireland are both absolutely consistent in their view that that would be massively damaging to the Northern Ireland economy.
But there is a separate issue that the Good Friday agreement involves, and it is very different in the Northern Ireland context from anywhere else in the United Kingdom: the whole question of identity. Identity matters in the Northern Irish context: identity and respect for people’s different identities is the heart and soul of the Good Friday agreement, and we simply cannot allow that to be damaged by crashing out of the European Union—a crash-out Brexit.
