The draft manifesto, seen by the BBC, says "a complete U-turn" on migration policy is necessary. It calls for measures to put an end to what it calls "illegal, culturally alien and anti-native mass migration."

These include plans to deport refugees and asylum seekers or to house them in central accommodation.

The draft contains a number of references to the controversial term "remigration", the mass removal of people with "non-German" backgrounds from the country.
