R North demolished the Switzerland "frictionless" border - as pushed by Tory MEP Daniel Hannan in particular:

What Hannan has relied on is an attractive picture (top) of a border crossing from Switzerland to France in the Hautes-Savoie department.
With that as his backdrop, he then tells us: "I cross the EU’s border with Switzerland every month", then claiming, "Not that I’d notice if I didn’t know it was there".
Hannan, though, is one of those MEPs who, although he gets paid the full scheduled airline fare to Strasbourg, opts to take the cheap, EasyJet flight from Gatwick to Basel airport, there being collected by a free luxury bus and taken into Strasbourg.
That way he can pocket over £500 every time he attends the parliament, adding and extra £200 or so to his profits, compared with taking the direct flight to Strasbourg. 
Now the thing is that Basel airport is actually Basel-Mulhouse international airport, which is the French side of the border.
He doesn't go into Switzerland at all.
If he did, when he was driven across the border, he would certainly know it was there. 
The Basel customs post is pictured above.
The border crossing used for his illustration is more than 250 miles from Strasbourg, on the other side of Switzerland.
To travel to travel to France, you have to drive south-southwest, away from Strasbourg.
The picture conveys a lie.
