Our first guest editor this Christmas is Lord Botham, Ian "Beefy" Botham, former England all-rounder, crossbench peer and UK Trade Envoy to Australia.Hear highlights from his programme in our Best of Today podcast, including an interview with the current England Cricket captain Ben Stokes, about the future of the test game. It was a chance meeting after a freak injury in 1977 which first put the sportsman on the path to nearly four decades of fundraising. Lord Botham reflects on that moment and looks at advances in the treatment of childhood leukaemia, a cause for which he has raised millions of pounds, with the BBC's medical editor Fergus Walsh.
