Berlin: The head of the far-right Alternative for Germany (AfD) says Berlin should send rejected asylum seekers and illegal immigrants to islands outside Europe and turn its refugee office into an emigration bureau.

The influx of over one million migrants last year fueled support for the AfD, which now has seats in eight of Germany's 16 state assemblies and is expected to make a strong showing in state votes next month in Berlin and Mecklenburg-Vorpommern.

Party leader Frauke Petry made the suggestions in an interview with the Bild newspaper published on Saturday.

"Illegal migrants and asylum seekers whose applications are rejected will be accommodated on the two islands outside Europe that are protected by the United Nations," Petry added, without naming the two islands she had in mind.
