I am not at liberty to say who said what at a European Council meeting any more than I am at liberty to say who said what at a Cabinet meeting. For anyone who does follow this session of a chamber, if anybody goes on the radio or television and tries to assert that a non-denial of something that somebody is alleged to have said at a European Council by me is confirmation, it is not. Those meetings are confidential.

I have been asked a few times what would happen in the hypothetical scenario of the United Kingdom crashing out of the European Union without a deal. Of course, I do not know for sure - nobody knows for sure - what would happen in that scenario. It will depend on various factors other than that. However, I can say that we have made no preparations for a hard border between Northern Ireland and Ireland and no preparations for physical infrastructure, checks or customs controls between Northern Ireland and Ireland. Even in the event of no deal, we believe the United Kingdom continues to have obligations under the Good Friday Agreement. We have obligations under the Good Friday Agreement as co-guarantors. We also recognise that the UK will have obligations under WTO rules and we will have obligations to protect our Single Market and our customs union, which obviously creates a problem. It creates a dilemma. Those are the conversations we have to have as to what might be done in different hypothetical scenarios.
