Whilst your top brass have decided against using the term 'electoral reform' in describing the planned AV referendum, you don't seem to mind using 'First Past The Post' to describe the current system.
Could you explain precisely what 'post' the winning candidate 'passes'? 45%? 40%? Oh hang on, they don't pass any post. I can understand why you do not use the rather academic 'simple plurality' term, but how about something more suitable such as 'the present system' or the (somewhat inelegant) 'winner takes all'.
