Micheál Martin became Ireland’s taoiseach (prime minister) for the second time in his political career on Thursday, a day later than planned.

Ireland’s parliament has succeeded in electing Micheál Martin as Taoiseach after a delay caused by unprecedented chaos in the chamber, kicking off a new government bracing for US trade challenges. The centrist Fianna Fáil leader’s coalition is preparing an “all-out diplomatic and trade offensive” to persuade US President Donald Trump to back off from his tax and tariff threats against the EU country where many large US technology and pharmaceutical companies are based.

Micheal Martin was appointed Ireland's new prime minister on Thursday after lawmakers belatedly backed him following a bitter row over parliamentary speaking rules that had delayed the vote.
