DUBLIN (Reuters) - Irish Prime Minister Leo Varadkar on Tuesday called a parliamentary election for Feb. 8, pitting his record on Brexit and Ireland's fast growing economy against struggling services in a contest polls suggest is too close to call.

Varadkar's Fine Gael and the fellow center-right Fianna Fail are closely matched in opinion polls, and some distance ahead of their other rivals, increasingly the likelihood that one of the two parties with similar policies on the economy and Brexit will lead to another minority administration.

After Britain's tortuous exit from the European Union dominated politics in neighboring Ireland following the last election in 2016, Varadkar sought to put Brexit at the center of the campaign. He also acknowledged more had to be done for people to feel the strength of the economy in their pockets.

"Brexit is not done yet. In fact, it's only half-time," he said in a speech in front of government buildings.

"The next step is to negotiate a free trade agreement that protects our jobs, our businesses, our rural communities... The capacity to do everything else that needs to be done - health, housing, climate action, tax reform - depends on achieving this outcome."

Varadkar, 40, became the once-staunchly Catholic country's first gay premier in 2017 when his party hoped a generational shift could lead them to a first ever third successive term.

He highlighted his success so far on Brexit, where a hard border between EU member Ireland and British-ruled Northern Ireland was avoided, as well as his own high profile in a video posted on Twitter that began with clips of international broadcasters saying his name.

Fianna Fail, which has swapped power with Fine Gael at every election since the state's foundation a century ago, focused on anger among some voters over a health service bursting at the seams and a dysfunctional housing market where rents have become prohibitively high for many.

"It clearly is a time for a new government that will really focus on tangible improvements in health, housing and reducing the cost of living," Fianna Fail leader Micheal Martin told reporters.

Fine Gael has led a minority government since 2016 through a cooperation deal with Fianna Fail - its fiercest rivals as far back as the country's civil war in the 1920s - after neither came close to forming a working coalition last time out.

Fine Gael and Fianna Fail refuse to govern with Ireland's third largest party Sinn Fein, once the political wing of the Irish Republican Army (IRA), meaning smaller parties such as the resurgent Greens could decide who leads the next government.

Analysts say one of the two big parties would need to move to a percentage share of the vote in the mid-30s from the 25% to 27% range they are currently polling to form a multi-party coalition and avoid another 'confidence and supply' deal.

"All of the polls are telling us that the fragmented party landscape is still there," said Theresa Reidy, a politics lecturer at University College Cork.

Ratings agency S&P Global, which handed Ireland back its double-A sovereign debt rating in November, said in a note that the election was unlikely to sway economic policy, regardless of the outcome.
