Parkbrake Operation
How does the parkbrake work?
Is it one drum with brake shoes that opreates on both rear wheels or one drum for each of the rear wheels?
Also how is it activated/deactivated electrically?

The insides of the rear brake discs form small drum brakes. The electrical actuator is a screw jack arrangement that pulls a cable to each wheel.

BTW, If you keep the park break botton pressed down when you turn off the ignition, the park brake is not applied. Useful in the winter when there is a chance the park brake can seize in very cold conditions.
Remember to put the car in gear!

Thanks for the information so far.
When I stop in traffic, as I have an automatic, I manually put the parkbrake on to prevent creep (I leave the vehicle in drive), rather than let my foot remain on the foot brake (which I believe can lead to brake disc warp on some types of vehicles).
Once I want to start moving I then let the vehicle automatically disengage the parkbrake by putting my foot on the accelerator.
This is the first vehicle I have owned that has an automatic gearbox although I have driven automatic a number of times on trips to the States.
It is also my first encounter with an electric parkbrake and at that one which automatically releases.
Is technique described above the same as that adopted by others with automatics?

on a side note, does anyone else experience a slight roll back / forward once the park brake is applied and the foot brake released? don't seem to remember it from early on into ownership - manual 'box BTW

Being the sensible guy that I am 8) I left my car handbrake off at Christmas when the temp was down at minus 11. ANyway I put it in 2nd gear but the car continued to roll forward, albeit slowly. ended up having to apply the brake. The car was on a hill but it wasn't overly steep. Is this normal or do I have a problem?

Beacuse of the nature of the drivetrain and the suspension - differentials etc. - a small amount of movement will be possible once the handbrake has been applied and the footbrake is released.
It feels like it moves much more than it actually does - more a rocking motion. Try coasting to a stop, then applying the parkbrake just before the vehicle stops.....it will stop abruptly, and rock a bit.
