Budapest has slammed the European Commission's decision to withhold grants from Hungarian universities as "unacceptable and intolerable" in the latest spat between the two sides. The commission said last month that 21 Hungarian universities will no longer be eligible for the bloc's Erasmus grant funding, which allows students to spend terms at partner institutions abroad. The universities would also not be eligible to apply for funding for the bloc's Horizon Europe research exchange programs, the commission said. The decision is part of the wider freezing of EU funds for Hungary over corruption concerns.
