FF TD tells High Court Sinn Féin President Mary Lou McDonald was not defamed in tweet

Fianna Fáil TD Declan Breathnach has denied he defamed Sinn Féin President Mary Lou McDonald in a tweet he published in 2018.

Ms McDonald has launched High Court defamation proceedings against the Co. Louth TD over a post he published on Twitter on October 11, 2018, in reply to a tweet she had posted in support of the now-retired Garda Maurice McCabe.
