The U.K.'s withdrawal from the EU should be put to a second public vote to overcome the current impasse, the former prime minister of Finland told CNBC Monday.
The Brexit deadlock continues after Prime Minister Theresa May presented some changes to her plan to leave the European Union on Monday afternoon. This comes after U.K. lawmakers overwhelmingly defeated her proposals last week.
"I still think there are only three options on the table: Number one is the deal as it stands, number two is the hard Brexit ... and number three, basically, is a new referendum," Alexander Stubb, who is currently the vice president of the European Investment Bank, said at the World Economic Forum in Davos, Switzerland.
"(If I was) the prime minister of the United Kingdom, I would go back to the people, because the decision of having a new deal is as big as leaving the European Union," he added.
Some U.K. lawmakers have been pushing for another referendum on Brexit, arguing that people now have a better idea of what leaving the European Union really means.
Speaking in front of the U.K. Parliament, May said that it's the government's duty to implement the decision of the first vote.
"I fear a second referendum would set a difficult precedent that could have significant implications for how we handle referendums in this country," May said.
