Ireland’s deputy prime minister, Micheál Martin, has criticised remarks by the former Democratic Unionist party leader, Arlene Foster, who said Joe Biden “hates” the UK. Martin said Foster was “wrong”, saying her remarks about the US president were “misplaced” as Biden did not hate anyone. “I’m very surprised by that comment,” Martin told RTÉ’s This Morning on Friday. “The one word that you do not associate with Joe Biden is the word ‘hate’. He’s the antithesis of that. He’s the opposite of that. He always speaks about the dignity of every human person. He’s more love than hate by a country mile.” Biden has spoken about the importance of treating everyone with dignity in each of the three speeches he has given on his four-day trip to the island of Ireland. Martin said: “I think it’s a wrong comment by Arlene. In fact, he often references his British heritage as well in terms of his uncle had been involved in the British navy and I think he gave a personal anecdote about that. So I think that was misplaced. He’s not that type of person.” Foster doubled down on her remarks earlier this week, saying on Thursday that the president had “disdain” for the UK. Martin, asked if Foster should withdraw her remarks, said: “Look, people make comments. I just have to say that I would refute it. I don’t have any sense, having met with Joe Biden on quite a number of occasions now, that he hates anybody.” Foster claimed she was reflecting on Biden’s past affinity with the nationalist position in Northern Ireland but others, including the taoiseach, Leo Varadkar, said the US president was proud of his Irish heritage but also of the special relationship with the UK. On Thursday, Biden risked irritating Foster and other critics further when he urged the UK to “work closer with Ireland” on strengthening efforts to sustain peace in Northern Ireland. The row over Foster’s remarks has marred the three-day love-in Biden is enjoying in the Republic of Ireland. He completes his visit on Friday with another heavy schedule in the west of Ireland, before leaving on Air Force One at about midnight. Before that, he will visit Knock at about lunchtime and pray at the nearby basilica and Marian shrine, an important Catholic pilgrimage site said to mark the apparition by Mary, the mother of Jesus, in 1879. He will then honour his son Beau, who died of brain cancer in 2015, during a private visit to the Mayo Roscommon hospice. The hospice has previously paid tribute to Beau Biden, a former Delaware attorney general. In 2017, Joe Biden travelled to the Mayo town to turn the first sod on the site for the new hospice complex, and he again paid tribute to the €6.3m palliative care centre when it opened two years ago. The US president will then visit a genealogy and heritage centre established to help descendants of Irish people who emigrated to the US, including his ancestors on his father’s side, before a final keynote speech outside a cathedral in Ballina.
