The High Court was told today that a defamation action taken by actress Maureen O'Hara's former personal assistant against Ms O'Hara's nephew has been settled.

Carolyn Murphy from Bantry in Cork, had sued Charlie Fitzsimons over four separate public statements made by Mr Fitzsimons, who lives in Kinna in Sweden, between August 2012 and 19 January 2013.

Ms Murphy's lawyer Tom Hogan told the High Court the matter had been settled subject to a statement being read to the court.

Mr Fitzsimons' barrister Rossa Fanning then read a statement to the court in which he said Mr Fitzsimons had made a number of statements questioning the integrity and honesty of Ms Murphy.

He said Mr Fitzsimons accepted such allegations were totally without foundation, he unreservedly withdrew any imputations to the contrary and apologised to Ms Murphy for the distress and anxiety that the false allegations had caused to her.

The court heard Mr Fitzsimons also undertook not to repeat the false allegations in the future and had agreed to pay appropriate damages to Ms Murphy in full and final settlement of the proceedings.

Ms Justice Iseult O'Malley struck out the case.

In a statement afterwards, Ms Murphy's solicitor Paul Tweed said she was very satisfied with the categoric and comprehensive retraction of and apology for "totally unfounded allegations" made relating to her work and support for Maureen O'Hara and the Maureen O'Hara Foundation over a number of years.

However, he said Ms Murphy remained extremely upset that these allegations were made in the first place and contributed to the breakdown of her lengthy personal and professional relationship with Ms O'Hara.
