Sri Lanka's President will step down after protesters stormed the presidential palace and set fire to the prime minister's house.

Joining Paul Henley to discuss these and other stories are Catherine Neilan, senior UK political editor for the Insider news website; and Daniel Glaser, a British neuroscientist and writer and director of Science Engagement for the Royal Institution in London.
