"Britain, today you can make history," Wilders wrote.
The leftist Guardian newspaper reminded its readers on Thursday of Britain's proximity to continental Europe — featuring a satellite photo taken at night.
German newspapers in particular featured strong pro-E.U. messages:
"The most important ballot in the world," Germany's Bild newspaper commented.
Conservative, Berlin-based newspaper Die Welt proclaimed: "We love you."
On the opposite side of the channel, French companies paid for an advertisement to keep Britain in the European Union: "Please remain, British friends!"
Denmark and the Netherlands
It's a message that was reflected throughout Europe, including in Denmark's Berlingske newspaper. Denmark fears that it will lose one of its biggest allies in the European Union in case of a Brexit.
Similar fears have emerged in the Netherlands, where the far-right has capitalized on Brexit to demand a similar referendum.
"Don't leave me this way," Algemeen Dagblad urged the British.
