Gary Lineker, Paddy McGuinness, Alex Scott, Emma Willis, Rylan Clark-Neal, Oti Mabuse and Tom Allen host the extravaganza, raising funds for good causes both in the UK and overseas. Highlights include two teams of celebrities leaving it all on the dance floor in a bid to be crowned The Greatest Dancer for Sport Relief and the rebirth of Killing Eve as Killing Steves, for a one-off Sport Relief spoof. The Battle of the Channels Celebrity Boat Race returns, and this year it's bigger than ever as BBC, ITV, Channel 4 and Sky compete for victory. In another sporting feat, Romesh Ranganathan takes on tennis legend Andy Murray in a crazy game of crazy golf. Plus, live music from artists including Rita Ora, John Newman and Celeste.
