Irish Language Commissioner Seán Ó Cuirreáin has announced that he is resigning from his position, citing concerns about the lack of progress in ensuring that Irish speakers can deal with the State in Irish.
Mr Ó Cuirreáin said that he felt he was left with no other choice but to resign from his role in ensuring the implementation of Irish language legislation.
He said his decision was a result of the State's lack of commitment to the protection of Irish speakers' rights.
Mr Ó Cuirreáin was the first person to be appointed to the newly-established position of An Coimisnéir Teanga in February 2004.
His resignation is due to take effect in February.
