It’s certainly not a requirement. I was surprised by how many interns of MEPs did not belong to their MEP’s party (maybe 50% or more ). (There was even one case of a Conservative MEP who had a Green intern.) This is even more true for the interns who work for the group as a whole rather than an individual MEP. However, of course, some MEP interns had got their internship through party connections with that MEP. Party membership certainly raises the odds significantly even without knowing MEPs.
