Sinn Féin TD Peadar Tóibín, from Meath, has resigned from the party.
He has tweeted:
It is with a heavy heart that I resign from Sinn Féin today. I have been a member of the party for 21 years. In that time I poured all my efforts into achieving Irish Unity & Economic Justice. This clearly is no longer enough. I will now help to build a new 32 County movement.
