United Kingdom Internal Market Bill

The hon. Member says it is not the fault of the EU, but can we just remind ourselves that it was the United Kingdom Government who gave an absolutely cast-iron guarantee that we would put up no infrastructure on the border between north and south in Ireland? It was the EU that kept threatening to do that, even though alternative arrangements could be developed to obviate that need. I fail to understand why people just do not want to believe that, except that they want to blame the United Kingdom Government, not the EU.
