Poland under pressure of EU to accept a larger share of the 160 000 illegal immigrants that arrived only at the last 5 months in Italy.
If the president was a weak slave of Bruxelles like Komorowski, probably poland would receive a amount of immigrants equivalent to Kutno. Remembering that the bulk of those immigrants come from countries dominated by Islamist Radical factions that have the declared purpose of infiltrate in Europe, like Al Shabab (somalia) or Boko Haram (Nigeria and Chad).
But Duda is a strong man. He will not accept silly demands from Bruxelles that can endanger his own people.
Fortunately now Poland have a good president and a good man that can avoid the worst for the country.
