The Stockholm stock exchange fell across the board, with industrial companies and banks leading the decline. The broad OMXS-index retreated 0.7 per cent.
The Paris stock exchange fell amid concerns over the new election called in the wake of the EU parliamentary election.
Nearly all companies on the OMXS30-index, comprising the most traded shares, were traded on the minus side. Among the losers, Kinnevik, the power company of the Stenbeck family, fell 3.6 per cent, medical technology company Getinge dropped 2.9 per cent, and major bank Swedbank declined 2.1 per cent.
Only four companies bucked the trend. Property company SBB topped the list, up 1.2 per cent. Bearing manufacturer SKF rose 0.2 per cent, while mining giant Boliden and car safety company Autoliv both advanced 0.1 per cent.
Outside the large-cap list, defence conglomerate Saab fell 3.2 per cent after the recent sharp gains for the share.
Also, on the leading European stock exchanges, it was a sea of red. The largest decline was for the CAC 40-index in Paris, down over 1.5 per cent, driven by a slump for banks such as BNP Paribas and Société Générale. At the same time, the euro weakened against the dollar.
The development is a reaction to French President Emmanuel Macron's decision to dissolve the country's parliament and call a new election. The decision was made after Macron's liberal party suffered a significant defeat against Marine Le Pen's far-right National Rally party in the EU election.
The focus for the week lies in the signals the US Federal Reserve will send after its monetary policy meeting on Wednesday.
