Since the EU enlargement in 2004, where ten new countries joined in the single-largest expansion to date (Cyprus, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia and Slovenia), the UK has experienced mass immigration from Poland (see Poles in the United Kingdom). It is estimated that the Polish British community has doubled in size since 2004; with Poland now having overtaken India as the largest foreign-born country of origin in 2015 (831,000 Poles to 795,000 Indian-born persons). Anti-Polish sentiment in the UK is often related to the issue of immigration. There have been some instances of anti-Polish sentiment and hostility towards Polish immigrants. The far-right British National Party argued for immigration from (Central and) Eastern Europe to be stopped and for Poles to be deported.
