Available for over a year

Turkey, Saudi Arabia and Pakistan have signed a major defence pact in Mecca, saying an attack on one is an attack on all three. A former advisor to Turkey's president tells us what he thinks his country gets out of such an agreement. Also in the programme: after the London-based head of Google DeepMind decides to step back, what does his move mean for the UK AI sector? We hear the views of the regulars in Soho about Westminster Council's plan to reduce 'vertical drinking', and we remember the life of William Orbit, groundbreaking producer behind the music of Madonna, Blur and U2.
