In a September 2023 interview with TheJournal.ie, Duffy likened a proposed reintroduction of an eviction ban (with exemptions for landlords where the property was needed for 'a relative') to communism, stating "Well then it turns into a communist state, that’s what you are talking about. So we purchase everybody’s property, is it?"[7]
