I'm up for promotion at work but part of the process will involve a review of my CV. There are one or two things on my CV, which while not strictly false certainly don't convey the whole truth. What legally constitutes a lie and what might my employer do about it?

It is not unusual for such reviews to take place when promotions are offered. It is also not unusual for candidates to 'bend the truth' on their CVs, as was famously the case with Jeffrey Archer.
