BRUSSELS (AP) — Croatia's prime minister says European Union leaders could meet in January for a new Brexit summit once Britain clarifies exactly what help it needs to pass the deal in the U.K. Parliament.

Andrej Plenkovic said Friday that "if there is a need we can always convene, but nothing in that respect was concluded yesterday" during Brexit talks in Brussels.

British Prime Minister Theresa May canceled a vote in Parliament this week after it became clear the assembly would reject the Brexit deal she concluded with the EU.

EU leaders refuse outright to re-open the deal, but in a statement they did offer assurances about how it would work.

Plenkovic says that "text is a solid signal, first of all to the prime minister, but also to the U.K. Parliament."
