A brand new Parliament heads back to Westminster this week, and the current tensions between Iran and the US are sure to dominate the conversation. We hear from the Deputy Head of Chatham House’s Middle East programme Dr Sanam Vakil, and the former Middle East Minister Alistair Burt on how the UK should respond. Elsewhere, as more people throw their hat in the ring to be Labour’s next leader, the MP for Wigan Lisa Nandy tells John why she’s running. And it’s not just Lisa who has leadership aspirations. The new Lib Dem MP for St Albans Daisy Cooper isn’t ruling anything out.Our pundits this week are Katy Balls of the Spectator, former Boris Johnson adviser Guto Harri, and Sienna Rodgers of Labour List.
