Cornwall Council has condemned the Government's decision to cut all its funding for the Cornish language.
The Government had provided up to £150,000 a year to support the language since it was recognised under the Charter for Regional and Minority Languages in 2003.
But they have now withdrawn all money, with immediate effect.
In recent years the grant has been used to support the development of the language, including funding a range of educational activities.
The Council has now received a formal letter from the Department of Communities and Local Government stating that it was not providing any further funding to support the development of the Cornish language .
