A large majority of Dutch nationals are opposed to dual nationality, but people with an immigrant background are less likely to do so, according to research by the national statistics office CBS.
Some 64% of people think immigrants who become Dutch should give up their original nationality and 73% think government ministers should not have dual nationality.
However, people who have immigrant roots are less likely to oppose dual nationality than the native Dutch. Of immigrants with a western background, 59% are opposed to dual nationality. Of those of non-western origin, only 28% think people who become Dutch should give up their original passport.
Some 1.1 million people in the Netherlands have dual nationality and the government is planning to introduce measures to combat this.
In a DutchNews.nl poll earlier this year, only 19% of the over 2,000 people who took part thought dual nationality was a bad thing.
