As Rafael Bear revealed in his column  this week, Ed Miliband has been taking tennis lessons, possibly to keep up with our already-quite-good-at tennis prime minister. But he's entering a dangerous game. It turns out David Cameron's tennis skills are merely the tip of a giant iceberg of sporting talent. Here are some further classes for Miliband to enrol himself in...
1. Badminton. Aamir Khan once described the sport of badminton as "like ballet dancing, requiring a lot of control, strength, mind play and measured movement". But his definition was too restrictive. Sometimes it can also be like Morris dancing.
2. Cricket. David Cameron plays cricket. He is so not scared of that ball. Small boy looks on, possibly in awe.
3. Swingball. David Cameron kicks back, playing a lonely game of swingball with his tie.
