What's going on at Silverstone and why was its place on the Formula One calendar in doubt? That's the question assistant editor Lee Boyce and broadcaster Georgie Frost tackle this week. It looks like the future of the F1 race in Northamptonshire has been secured – but what's behind the economics of the iconic track and its owners? We are joined this week by former British F1 driver Mark Blundell – 1992 Le Mans winner and three-time F1 podium finisher. He gives us his views on Silverstone, how technology has changed the face of motor racing substantially since the 1990s and why – aged 53 – he decided to get back behind the wheel, competitively. We look into the Silverstone contract, new races for 2020, the threat of a London Grand Prix, why it is important to the economy – and the impact paid-for TV is having on sport.
