Swedish Prime Minister Ulf Kristersson has expressed concern over immigrants who are unwilling to defend Sweden.

He believes that becoming a Swedish citizen is too easy and that people can attain citizenship without understanding the obligations and values that come with it.

Kristersson's remarks have been criticised by the opposition, who argue that such statements could divide the country.

The Social Democrats accuse Kristersson of dividing the country by implying that immigrants are less willing to defend Sweden than those born in the country.
