Biden ends Ireland trip in County Mayo

US President Joe Biden has concluded his official visit to Ireland with a speech to thousands of people, with crowds lining the streets in the town of Ballina waving Irish and US flags.

Also in the programme: Why Germany is shutting down its three remaining nuclear power stations - in contrast with other nations in Europe which are expanding their nuclear capacity.

And we hear about the dangers of reporting in Mexico, where dozens of journalists have been killed over the past 20 years. One group of journalists has been investigating the links between the drug cartels and politics.

Joining Gary O'Donoghue to discuss these and other stories are Karen Von Hippel, director-general of the Royal United Services Institute, and Alan Posener, a columnist from the German newspaper Die Welt.
