A Cavan Sinn Féin councillor says the government must begin plans and preparations for a United Ireland.
Local Sinn Féin councillor, Stiofán Conaty, has said partition has failed the people of Ireland, north and south.
It comes as Sinn Féin will bring an Irish Unity Bill to the Dáil on Tuesday.
Sinn Féin's Dáil bill follows on from numerous county and city councils around Ireland having officially and formally called on the government to begin plans and preparations.
Cavan County Council was among the first to make the move, in a motion proposed by Cllr Conaty and supported by Sinn Féin councillors Damien Brady and Noel Connell, as well as Aontú.
Cllr Conaty says the government has a historic opportunity to reunite the country.
