Denmark's minister for immigration Inger Støjberg says she is not surprised that fewer Muslims have been approved for Danish citizenship since the government introduced stricter rules in 2015.
According to research carried out by newspaper Politiken, 70 percent of new Danish citizenships in 2014 were to people from primarily Muslim countries. That figure has fallen drastically to 21 percent this year.
In the same period, Denmark has begun to allow double citizenship, increasingly the likelihood of nationalisation applications from Western countries.
Støjberg said the figures show that the curbs, which her ministry was responsible for implementing, have had the desired effect.
"There is no doubt that this is because the demands have been increased. For example, the language requirement, being able to provide for oneself, staying away from criminality and passing certain tests," she said.
