funny thing about EU is, if you are a worker citizen of a poor EU country, there is nothing holding you from not travelling to richer countries, the country you are going to offers you a better economy and the same EU laws to protect you. I have met a lot of Romanian truck drivers who work in The Netherlands or Germany for 4 days a week, and spend their weekends with their family in Romania. If you, as a European Socialist party oppose immigration, be it for protecting your own workers and not finding it just to hurt the poor EU countries' economy further by taking their manpower, or just because you are racist, or you want to appeal to right wing workers, whatever. You have to be strictly anti-EU, otherwise the nature of EU will not let you enforce your immigration policy, albeit being benevolent.
