New Yorkers could redraw the US’s political faultlines today if the left-wing frontrunner for city mayor, Zohran Mamdani, defeats former state governor Andrew Cuomo. Donald Trump has already set his sights on Mamdani, threatening to withdraw federal funding form New York City if the 34-year-old democratic socialist wins the mayoralty. We hear from one of Mamdani’s informal advisers, Patrick Gaspard. 

Also on the programme: the BBC exposes an organised crime network behind high street shops involved in fraud, tax evasion and illegal working; and Dick Cheney, one of the most powerful US Vice Presidents of all time, has died. We hear from a close aide who was with him on 9/11.
