South Korea: Horrific stampede in Seoul

South Korea is in mourning following the deaths of more than 150 people who'd been celebrating Halloween. President Yoon has promised a thorough investigation of the crush in a narrow alley in the capital, Seoul.

Today, we're joined - for the rest of the programme - by Azadeh Moaveni, an Iranian-American writer and director of the Gender and Conflict Project at the International Crisis Group think-tank and by Simon Lancaster, a British speechwriter and author.
