A new development this week in the UK government's efforts to deregulate the City of London may be relaxing the ring-fencing around banks, according to a person familiar with Treasury plans. Editor Katherine Griffiths joins this week and asks whether the move is "a small whimper that they're packaging as a big bang." Plus, a conversation with the new Lord Mayor of London, Nicholas Lyons. He shares his vision for the City and says it's time to work together to take advantage of regulatory freedom and capture what he considers the positive aspects of Brexit.
