DUBLIN: US President Joe Biden on Wednesday began a nostalgia-filled tour of the Republic of Ireland, jetting in from Northern Ireland where he pushed for an end to crippling political paralysis in the British province.

Biden emerged from Air Force One at Dublin airport to driving wind and rain, and was greeted by the Irish Taoiseach (prime minister) Leo Varadkar and a sea of black umbrellas.

The 80-year-old president, who regularly mentions his Irish roots, calls Ireland “part of my soul” and his visit includes trips to the hometowns of his 19th-century ancestors. He will also meet Irish head of state Michael Higgins and address a joint sitting of both houses of the Oireachtas — the Irish parliament — before heading home late Friday. Despite the sentimental nature of his Irish visit, Biden was keen to underscore the seriousness of his trip.

The priority, he said, was “to keep the peace” in Northern Ireland, 25 years after a landmark peace agreement that ended three decades of deadly sectarian violence over British rule.

He used a speech at a new campus of Ulster University in Belfast earlier on Wednesday to promote the benefits of enduring peace and investment.

But he still faced heated criticism from pro-UK hardliners. The UK government also downplayed suggestions his one-night-only trip to Belfast was a snub to the so-called “special relationship”.

“I hope the (Northern Ireland) Executive and Assembly will soon be restored,” Biden said, urging feuding leaders to restore power-sharing government which has been suspended since February last year.

Biden touted the “unlimited possibilities” for investment and growth offered in Northern Ireland, 25 years on from the Belfast/Good Friday Agreement. But, he said, peace and stability must always be guarded, warning that the January 6, 2021, riot at Congress in Washington had proved that in every generation, “democracy needs champions”.
