Episode description
Has trade with the EU increased since Britain left the European Union? Tim Harford and the team look at a claim suggesting just that. There’s a row over the renaming of a street in North London previously called Black Boy Lane – but how much has it really all cost? Also are there more pensioners in “millionaire households” than pensioners in poverty. And mathematician Hannah Fry talks about a new study suggesting cases of ovarian cancer can be detected by looking at spending on loyalty cards.
