What does "centrist" mean here?
sounds like "non-populist".
Well, being euroskeptical seems one of the features of a populist party nowadays, so by definition it will be difficult to find a party that's centrist and "anti-EU". Dutch CU is a non-populist and centrist euroskeptical party but I don't know whether their soft euroskepticism would truly qualify them as "anti-EU". I personally tend to see RRWPs such as DF and PVV as "centrist" economically but I guess that's not what the one who posed this question really means.
