After British Labour party leader Jeremy Corbyn suggested that the Elgin Marbles be returned to Athens, Hannan criticised Corbyn for "national ", writing in ConservativeHome that this confirms the view that Corbyn will "always and everywhere back another country against his own". Hannan similarly criticised former Downing Street press secretary Alastair Campbell for "cheering for the other side" after Campbell retweeted positions of Irish Taoiseach Leo Varadkar on social media while Campbell, writing in The New European, suggested that Hannan was "claiming a monopoly on patriotism."
