The man with the unlikely name is the very charismatic but openly racist politician and leader of the far right Leefbaar Nederland, the largest political party in Rotterdam.
It's a mystery why he got so popular - he favours zero Muslim immigration, wants to cut the annual number of immigrants accepted to 10,000 from 40,000, and has campaigned for a key anti-discrimination clause to be removed from the constitution.
Yes, in Rotterdam, where almost half of the 600,000 population are of non-Dutch extraction, he won 17 of the city council's 45 seats at the beginning of March, ending the ruling Labour party's post-war dominance.
Bram Peper, the ousted mayor of Rotterdam, said: "I don't know what's going on, but something is terribly wrong in Rotterdam."
