If the UK is to leave the customs union and single market and the Republic of Ireland is not, there have to be customs controls at the border between the Irish Republic and Northern Ireland unless it is placed somewhere else. The only other place they could be located is between the ports of Great Britain and Northern Ireland. That is what Mrs May said no British Prime Minister could ever do.

Since art 50 (2) of the Treaty on European Union required the negotiators to take account of the framework for the UK's future relationship with the EU which was supposed to be expressed in the Political Declaration, the EU negotiators were mandated only to flesh out the details of that framework. That is the substance of their draft treaty of 18 March 2020. When Johnson, Gove, Frost and company refused to consider that draft the talks became deadlocked allegedly on state aids, fishing and dispute settlement.
If that surmise is right the United Kingdom Internal Market Bill could have been intended to jolt the EU into making concessions. The threat is that if nothing is done the Irish government will be forced to police the border with Northern Ireland that could lead to political instability in the Republic as well as (possibly but from the Briitish point of view much more affordably) in Northern Ireland. If that is the tactic it is not clear that it will work for the Commission announced at 10:00 this morning the first step in taking legal action against the UK.
