Thank you. I'm sure that the First Minister will have read, with concern, details of the UK Government's plans for a so-called 'doomsday' Brexit, under which the second-worst scenario of us leaving the EU without a deal would lead to the port of Dover collapsing, food shortages, fuel shortages, and the NHS running out of medicines within two weeks. Can I ask the First Minister what discussions you've had with the UK Government about these so-called 'doomsday' plans? And given that the UK Government's handling of Brexit is becoming more shambolic by the minute, what assurances can you offer that we will not encounter disruption to key services like the NHS in Wales?
