Health, Russia, Policing, the House of Lords, HMS Erebus

Health Minister Mabon ap Gwynfor joins us for the first time in his new role. St Petersburg hosted its annual economic forum this week. IMI media group's Hadley Gamble went to Russia and tells us all about it. And what next for policing after Henry Nowak's murder? USW's Professor Christian Kaunert discusses. Only a few years since being made a baroness, Carmen Smith has put forward a bill to replace the House of Lords with an elected chamber. She explains why. HMS Erebus was launched from Pembroke Dock on June 7 1826. She disappeared on a polar expedition in 1848 not to be found until 2014. Dr Claire Warrior from Royal Greenwich Museums says what happened is still a mystery.

And in our series meeting new MS's, Paul Rock from the Greens is with us.
