The Montenegrin government has blocked a decision to grant the debt-ridden Montenegro Airlines a further 500.000 euros. The Ministry of Finance says it came to the decision after the State Aid Control Authority concluded that the payment would constitute as illegal state aid, following three years of restructuring at the company. The European Commission has previously said it was monitoring state aid grants to the carrier. Last week, Montenegro Airlines payed its staff two late monthly wages in order to avoid a planned strike by its pilots. It is believed the carrier took out a loan in order to make the payment. Montenegro Airlines' debt currently stands at over seventy million euros.
