Britans voted in favour of Brexit at a 2016 referendum called by former Prime Minister David Cameron, who wanted the United Kingdom to remain in the EU. He resigned after the referendum and left her successor May, who was also against Brexit, to agree a "divorce" deal with the EU.
"It was a completely unnecessary referendum and we are all living with the consequences of the bad political assessments of the previous British prime minister," Plenkovic said at a security conference in Munich.
"Frankly speaking, Theresa May is actually cleaning up someone else's mess," Plenkovic said, adding that an orderly and predictable Brexit was important for Croatia.
"We regret that decision. We think it is not good, it is indeed bad both for Britain and for the EU, but we are working with other members to ensure that it is conducted in an orderly fashion," he added.
Apart from speaking about Brexit during a discussion on the future of Europe, Plenkovic also discussed the matter with the European Commission's chief Brexit negotiator Michel Barnier.
