Micheál Martin’s leadership of Fianna Fáil is not under threat after the party’s disastrous results in two byelections over the weekend, a junior minister has said.Timmy Dooley said he didn’t agree “at all” that the Taoiseach was no longer the right person to lead Fianna Fáil into the next election. “You cannot take byelections as somehow an indication as to how we might perform in a future general election,” Dooley told RTÉ’s Morning Ireland on Monday.Fianna Fáil suffered a major defeat in Dublin, where it recorded its worst byelection performance as John Stephens took just 4.2 per cent of the vote. In Galway West, Cillian Keane secured only 8.8 per cent and was never in contention.Fine Gael’s Seán Kyne clinched the Galway contest, while the Social Democrats’ Daniel Ennis was elected in Dublin.Dooley said Fianna Fáil would “have liked to have done much better in Dublin Central, a little bit better in Galway”.The Minister of State at the Department of Agriculture added: “Every member of the party has to take responsibility across the board, and we do.”Dooley said byelections are “very different to a general election”.“First of all, the turnouts are generally very low, and in a case like this where we have a stable majority in Government, the electorate know that they’re not going to change the outcome of the Government.”Dooley added: “It’s only about 15 months since we last put our manifesto to the Irish people, we got 48 seats, we’re in Government.”The Clare TD said Fianna Fáil was focused on working alongside its Coalition partners of Fine Gael and Independents to address “this really difficult period of time that we’re working through as a result of the crisis in the Middle East” and “the spiralling increase in the cost of oil”.“What all of us need to do now is focus on the budget, focus on putting in place a package of measures that meet the needs and expectations, insofar as we can, to address this crisis that has been foisted upon us as a result of the activities of others in the Middle East, and what’s going on between Russia and Ukraine.”Louise O’Reilly, Sinn Féin TD for Dublin Fingal West, denied Mary Lou McDonald’s leadership of the party was at risk after it also failed to secure a seat in either byelection.O’Reilly told Morning Ireland Sinn Féin will conduct “a post-election review” but insisted McDonald has the support of the party.“Every aspect of the election will be reviewed but, in terms of the party president, we as members of Sinn Féin get the chance to elect our leader at our ardfheis. That happened three weeks ago, and Mary Lou is the choice of the membership and of the parliamentary party, and indeed beyond that.”O’Reilly, the party’s spokesperson on social protection, rural and community development, said people should not “read too much into ... one or two byelection results”.“It’s not going to tell us very much because we know ourselves that the byelection results are very rarely reflected in the general election results, even when they come in very quick succession.”When it was put to her that Sinn Féin sometimes struggles to explain where it stands on issues such as immigration, abortion and the environment, O’Reilly denied the party had “an identity crisis”, saying it was “firmly a Republican, left, united Ireland party”.She said she was “not trying to dress this up” but thousands of people “did vote for Sinn Féin” and, with 39 TDs, it remained “the largest party of opposition by a considerable margin”.
