Based upon MP Lembit Opik who was going out with Sian Lloyd the weather girl and dumped her for a cheeky girl.
It basically means someone who has been a bit of an idiot, made mistakes everyone else can see but is oblivious to them or can just be applied to anything anyone that is stupid.
As in: "You Lembit" or "He's a right Lembit" or "You sneaky cheating Lembit!"
