European stocks closed Monday lower, as investors monitored signs of thawing tensions between the U.S. and North Korea and reacted to renewed political turmoil in Italy.
Italian stocks closed 2.07 percent after initially opening the session higher. This after news of a dramatic setback for the country's populist parties.
The leader of Italy's largest political party called for the country's president to be impeached after choosing to veto a choice for economy minister. Luigi Di Maio of the anti-establishment Five Star Movement said President Sergio Mattarella had prompted an "institutional crisis" by rejecting euroskeptic candidate Paolo Savona.
No major political group has been able to form a majority in Italy since elections in March, leaving the euro zone's third-largest economy without a government.
The euro initially gained ground on the news but soon fell as traders contemplated a political stalemate and another election.
