The likelihood of a no-deal Brexit has increased significantly since Boris Johnson was appointed Prime Minister of the United Kingdom, with Ireland's Minister for Fiance Paschal Donohoe recently saying that it is a "very credible and material risk now".
Asked by the BBC on Thursday if he would resign after losing a confidence vote, Johnson declined to answer the question.
