No you dont, because when you move past the parked car, there wont be anybody coming from the other way to indicate to, because if they are close enough that you have to warn them you are moving out, you will of failed anyway and following traffic will be aware you intend to drive past the parked car, because you havent indicated left to pull in behind it.
All three tests I've taken (Bike, Car, HGV) I've been told not to do it.
This is going to be the same as the passing on the left fiasco,

So at the very least "good drivers" or "advanced drivers" view it as bad practice even after you have passed your test, as your road positioning, speed and observation will of told everyone what you are doing, and indicating then brings an element of doubt to you actual intentions.
The bike link is a little different as you get people arguing about being as safe as possible due to ignorant car drivers not paying attention, which in itself is true enough seeing as half of them dont know when to indicate or not.
