Fine Gael TD Olivia Mitchell has confirmed she will retire from politics at the next general election.

In a letter to Fine Gael constituents, Ms Mitchell said: “I believe now is the right time for me to pass the mantle to a new generation

“While this was a difficult decision for me to make, I am consoled by the knowledge that we have in the constituency a number of excellent potential candidates who are more than qualified to retain the seat for Fine Gael.”

Ms Mitchell said it has been an incomparable honour to stand in the constituency and said she would remain an active member of the branch.

Fine Gael will now have four candidates to stand at convention, including former minister for justice Alan Shatter.

Councillors Neale Richmond, Barry Saul and Josepha Madigan will also contest the selection convention.

A date has been set for October 2nd, with nomination papers distributed last week.

Fine Gael is said to be in favour of a two-candidate strategy because the constituency has been reduced from five seats to three.

Independent TD Shane Ross, Labour Minister for Communications Alex White and Independent TD Peter Mathews are all seeking re-election in Dublin-Rathdown.

Fianna Fáil has selected Senator Mary White, while Sinn Féin’s Sorcha Nic Cormaic is also contesting.

Green Party deputy leader Catherine Martin is also a candidate, as is People Before Profit’s Nicola Curry

In a statement, Ms Madigan said: “Olivia has been a tremendous representative for her constituents for almost 20 years. She has also been a role model for women looking to enter politics, including myself.

“She has been very influential in my political career, giving me invaluable advice and support during my successful council election campaign last year.

“I hope to continue her good work and if selected to contest the general election for Fine Gael, I know that I can count on her support.”
