Immigrants are making Germany 'dumber', according to a board member of the country's central bank.
Thilo Sarrazin claimed the 'limited education' of immigrants - coupled with their high birth rate - meant Germans 'are becoming dumber in a simple way'.
He said: 'There's a difference in the reproduction of population groups with varying intelligence.'
It is not the first time the 65-year-old member of the Bundesbank has caused controversy since he joined last year.
In October he described Muslim children as 'underclass' citizens.
'I don't have to accept someone who lives off a state they reject, doesn't properly take care of the education of his children-and keeps producing more little girls in headscarves,' Mr Sarrazin said.
