Voting with their feet
By Graham Davies

Shoe-throwing is the new heckling. Speakers and presenters need to sharpen up their acts and learn the language.

I'd hazard this ranges from flip flop (mild rebuke) to slipper (boring), steel toe-capped working boot (outrage), thigh-length PVC (not sexy enough) and on to a nice brogue (I wish you were Irish).

The conclusion is clear: if MI6 wants to secure early identification of radical dissenters now, they really need to stake out Stead Simpson.
