Sinn Féin has been forced to take down Co Tyrone posters featuring candidates for the election race in the Republic.
Placards for Donegal candidates Pearse Doherty and Padraig MacLochlainn were removed today after they were pasted on the back of Roads Service signs in Omagh.
Sinn Féin said they didn't know who placed the adverts but confirmed they had been promptly erased.
Omagh councillor Sean Begley said: "What I am led to believe is that there were two posters put up on the back of road signs and they were removed.
"I don't know who did it, anyone could have done it at the end of the day but they are our posters."
Omagh is on the main route from Dublin to north and west Donegal.
Mr Doherty is standing in Donegal South West and Mr MacLochlainn in Donegal North East.
"There is nothing to stop people putting up a poster if they want to, the problem was where they were," Omagh chairman Mr Begley added.
In previous elections Fianna Fáil posters were put up on lampposts outside Casement Park gaelic ground in west Belfast.
Fianna Fáil has considered formal links with the SDLP in the past but Sinn Féin are the only party which organises on an all-Ireland basis.
