Former Catalan leader Carles Puigdemont arrived in Copenhagen on Monday, defying a threat by Madrid to issue a warrant for his arrest if he leaves Belgium, where he has been in exile since a failed independence bid.

Danish broadcaster TV2 released an image on its website of Puigdemont being surrounded by reporters after his plane landed in Copenhagen Airport. Puigdemont is to take part in a debate on Catalonia at the University of Copenhagen later Monday.
