First ministers, chief ministers and ministers from Westminster, Jersey, Guernsey, the Isle of Man and Northern Ireland are due to spend the day on Friday discussing indigenous tongues spoken by minorities.
A spokesman for the Chief Minister’s department said that the names of those coming would not be released until later in the week because of security concerns.
The council’s work on the preservation of languages is led by Wales, where experts have been looking at the best examples of how tongues can be promoted.
Education Minister James Reed is due to address the summit on the place of Jèrriais in Jersey history. ‘I am pleased to be able to take part in this conference and look forward to speaking on how Jersey promotes its own minority language,’ he said.
