"Take back control of our borders" - but not our only land border with an EU country.
If the brexit nonsense is not stopped, there won't be a border on the island of Ireland, so not only can goods (which might be substandard rubbish from anywhere) freely cross that border, but people, including the entire population of Romania and Bulgaria who might travel freely to the Republic of Ireland, as they are quite entitled to do, can then take a bus or a train or just saunter across the non-existent border into NI and then go on to the rest of the UK.
How is that "taking back control of our borders"???????
