There's something in the air.
As the United Kingdom readies itself for a historic vote on its relationship with the European Union, other states of the 28-member bloc are making moves to set up their own.
In Italy anti-establishment party 5-Star Movement has called for a referendum on whether or not to keep the euro.
"We want a consultative referendum on the euro. The euro as it is today does not work. We either have alternative currencies or a 'Euro 2'," Luigi Di Maio, a vice president of the lower house of parliament, said on Tuesday night.
Though a referendum wouldn't automatically change the law in Italy, it would test the sentiment of the people.
Meanwhile, in France, National Front leader Marine Le Pen has said the UK's referendum is testament to the fact the EU is "decaying", promising to give France its own referendum if she is elected in next year's presidential election.
"I would vote for Brexit, even if I think that France has a thousand more reasons to leave than the UK," Le Pen said. "Because we have the euro and Schengen. Whatever the result, it shows the EU is decaying, that there are cracks everywhere."
And in Denmark, it was reported that the Danish People's Party want to take similar steps.
"If the British people vote ‘no thanks‘ to the EU on Thursday, a similar referendum should be held in Denmark," its leader Kristian Thulesen Dahl told local media.
