FIANNA Fail's treatment of senator Averil Power illustrates that "diversity of opinion" is not welcome in the mainstream political parties, according to former minister Lucinda Creighton.
The Renua leader today said the events surrounding Ms Power's departure from Fianna Fáil "sums up everything I know about politics".
And Ms Creighton admitted that her new party "wouldn't shut the door" to Ms Power but said they have had no conversations about her joining Renua.
"To my mind it sums up everything I already know about politics or at least the old political establishment, which is that diversity of opinion on really sensitive social issues, that different people have strong opinions on, that diversity of opinion is just not welcome in the old parties," Ms Creighton said.
"The passion of individuals like Averil Power is something to be welcomed in politics, not something to be feared. So that's my view on the matter," she added.
Separately today, Ms Creighton criticised Taoiseach Enda Kenny over conduct towards other deputies in the Dail.
During 'Leaders' Questions' today, Mr Kenny accused Independent TD Clare Daly of going on a "rant" about the proposed sale of the Government's 25.1pc stake in Aer Lingus.
Later, Ms Creighton said the Taoiseach should "show a suitable respect for our parliament", adding that Mr Kenny spoke in a "patronising way".
She added: "I think certainly the Taoiseach does not do himself any justice in speaking to people in that way."
Earlier in the Dail, Ms Creighton expressed frustration after the Taoiseach did not respond to her claims that Independent TD Catherine Murphy was being "silenced" by Siteserv.
It was reported this week that Siteserv wrote to the Ceann Comhairle seeking tat the Dail record be amended to address what it described as "unfound" and "false" accusations in recent speeches by Ms Murphy.
Ms Creighton called on the Taoiseach to "reject attempts to silence members of the House" by Siteserv and businessman Denis O'Brien.
Fianna Fáil already has a lack of female politicians but its brutal treatment of former party Senator Averil Power following her resignation means that it is likely to have a continued lack of female supporters for the foreseeable future.
