Most members of Denmark's parliament now support a measure in favour of dual citizenship that will be presented to the ministry of justice before the end of 2012.
If the proposal were approved it would mean not only allowing foreigners who qualify to take up Danish citizenship but also permit Danes living abroad (about 250,000 people) to retain their citizenship even if they apply for that of another country.
However voters are still lagging behind; according to a Gallup/Berlingske poll over half of the electorate is against dual citizenship.
Sweden and Finland both now accept dual citizenship but Norway still requires people to renounce their previous nationality if they want a Norwegian passport.
At present 20 of the 27 European Union states permit people to have two passports.
