Independent Senator Averil Power has launched a new attack on her former party, over their lack of resources for getting women involved.

Fianna Fáil has seen two resignations in as many days, after both Senator Power and activist Ken Curtin announced they were resigning from the party.

Senator Power's shock departure was discussed at a Fianna Fáil parliamentary party meeting this afternoon.

Yesterday she said it was not fit for government, and that the cynical approach by the party to the same-sex marriage referendum was the final straw.

"While I canvassing on the marriage referendum, I was struggling to give an answer as to where the party was", Senator Power told Sean Moncrieff.

"I really thought the party would change for the better" she said.

She said she was tasked with putting a strategy together to increase female participation in the party - but that nothing ever came of it.

"I kept raising private concerns", she said, but that it needed resources that were not given.

She added "I also felt that I was being used to some extent to cover up for the fact that there weren't women" in the party.
