It seems ironic, when we remember the sound and fury generated on both sides of the referendum campaign, that the biggest sticking point in the Brexit negotiations – the Irish border – is one that was hardly mentioned before the vote. As with so much in politics, how you see this conundrum depends on who you are and where you sit.

For them, avoiding a hard border eclipses any other potential goal of the Brexit negotiations.
