German car manufacturing. VW’s biggest engine factory is in Gyõr, Hungary. BMW is building in Debrecen, then there is also Mercedes. Hungary is also a major battery manufacturer since recently.
Couple that with some other industry, like the only non-Danish Lego factory in the EU for example, or others.
Cutting Hungary out from the customs union would cost a lot of people with a lot of power in the EU a lot of money.
Yeah it was not against you, only against WP, even if I was harsh with language. I should have made that clear.
Sorry and thanks for posting.
