Max Atkinson's party conference season prize competition

Max Atkinson is running a competition on his blog with prizes:

All you have to do is to suggest one object that any of the three main party leaders could use (or, in the case of Nick Clegg, could have used) to strike a chord with their audience during their 2010 conference speeches.

Keen anoraks are welcome to propose an object for each of the three party leaders, but one leader/object is perfectly acceptable.
