Varga warned that Hungary could rethink its position once it becomes a net contributor to the EU's budget, reigniting debate ahead of Hungary's elections next year.

“When we calculate that we will already be net contributors to the EU, the issue could get a new perspective,” said Varga, in an interview with Hungarian media. “Especially if the attacks in Brussels are continuous because of the choice of values.”

Varga did say that if a hypothetical vote were to take place this year for Hungary to join the EU now, he would “be among those who voted yes.”

Hungary joined the EU in 2004 and has always been a net beneficiary rather than contributor.
