Donegal County Councillor Frank McBrearty, who resigned from Fine Gael after less than two months in the party, has said he will sue Fine Gael for post-traumatic stress disorder.

Speaking to RTÉ’s Raidió na Gaeltachta, Cllr McBrearty claimed he was the victim of internal party bullying and was not welcomed into the party by some elected representatives.

The Donegal councillor said there were very heated discussions within the Fine Gael group on the council this week, regarding power-sharing agreements for the new council term.

Mr McBrearty claims that senior officials in Fine Gael offered him positions on three national committees in a bid to get him to stay in the party.

He said he was offered positions on the new Policing Authority, the Loughs Agency, and an unnamed national committee.

Cllr McBrearty added that he hopes to be part of a power-sharing agreement in Donegal County Council.

"I have to talk to the independents and the other groupings, Fine Gael included....If I am excluded from power-sharing I will make the council unworkable."
