Is Europe’s centre-ground shrinking?

As Sinn Fein enters coalition talks with Fianna Fail, economist Fredrik Erixon writes that the encroachment of fringe parties on the mainstream is a part of a wider European trend. What's more, he argues that the only the mainstream parties that adapt can survive. On the podcast, Fraser Nelson bats for Fredrik's thesis, and debates with Anne McElvoy, senior editor at The Economist.

Plus, is citizenship a privilege that can be revoked, or a right to anyone who identifies as British? Earlier this week, a group of Jamaican nationals - all of them holding criminal records - were due to be deported. A last minute judicial review saved some from boarding the plane, but a wider debate is raging about whether these people should be deported at all, with Jeremy Corbyn accusing the government of racism.

And last, what makes South Korea's cultural output quite so successful? This week Boon Jong-ho took home four Oscars for Parasite; and Professor Rana Mitter writes that it’s not just films that the country excels in – but also literature and music, with ‘K-Pop’ a global phenomenon. Rana joins the podcast from Oxford, together with Andrew Heskins, the founder of easternkicks.com, a review website specialising in Asian film.
