How successful has President Trump's America First policy been? On Business Weekly we assess the legacy of his first term and ask what the world wants from the next resident of the White House. We take a look at how effective Covid-19 tracing apps are in tracking and stopping the spread of the disease. Could technology like this be the silver bullet the world is waiting for? As the Hindu festival of Durga Puja begins, we consider how those businesses that rely on the celebrations for the income will cope this year. And we examine the sharp rise in the price of pets during lockdown. Presented by Lucy Burton and produced by Matthew Davies.
