Do you do this at round about ????

Sometimes do it. We have a roundabout adjacent to the divisional traffic HQ where under their noses a few drivers turn left from the O/S approach, its a historical thing dating back to when the road markings allowed for O/S and N/S lanes to permit this. Its now a risky approach but the cops don't seem to fussed.

The arrows on the road don't 'permit' anything, they're advisory.

1.  Why would someone going straight ahead be signalling right? That's not what the HC says.
2.  Are you saying I should not make a perfectly legal manoeuvre correctly, simply because other people do it incorrectly?

Huh?

1. If you exit after the straight on exit by definition you aren't going SO. Try again. I wrote And given that most people who exit a roundabout after a straight on fail to cancel their right turn signal to signal left - so drivers who wish to take the exit after the SO will usually correctly signal a right turn on entering a roundabout but fail to cancel it and indicate left after passing the exit before the one they intend to take. In simple terms, I mean failing to signal left for the 3rd exit after passing the 2nd. It happens all the time, but on smaller r/abouts without a small forest in the middle it's not too difficult to suss where they plan to go.

2. Legal? The HC informs us to approach a roundabout in the correct lane, taking guidance of any lane markings and arrows that may be there to guide us. I've never seen a road marking made up of a complete circle with an arrow pointing left, in the style of a pigs tail. But you carry on. Conscience & all that.

Surely it's only 270 degrees if you are in France.  Otherwise going all the way around the roundabout and then taking a 90 degree is 450 degrees.

See above re frame of reference. Some people are looking at the roundabout as a circle and how many degrees of that circle you do, so 90 would be left, 180 would be straight on, 270 would be right, 360 would be back to where you came from etc so 450 would be a loop then left.

Others are looking at the change in direction of the car, so 0 would be straight on, ie no change of direction, 180 would be back to where you came from etc, so 270 would be a loop then left. For the latter it's easier to think of a crossroads, or maybe a mini roundabout, where you can go straight with no actual change of direction.

Personally if I am doing a U-turn, I am going a full circle, just the same as if I turn my body full circle.  But hey...

For the point at hand, some might see doing what the OP describes as pushing in and selfish, but there have been lots of occasions when there has been traffic jams on the M4 because people are only using one lane on the slip road.

If you turn your body a "full circle" you're pointing the same way as you were before! If you do a half circle you're pointing the opposite way.

But if you're following a path and get to a circle, and go round the full circle, and exit along the path you came, you're going in the opposite direction!

If you think that doing a u-turn equates to turning in a full circle, you must get lost a lot...

Yes I have and will do, not a  massive queue either, about 8 to 10 vehicles.

At certain times of day this can be beneficial on a lights controlled roundabout near me. To save time one needs to pass through the right lane at least 2 cycles of the lights ahead of the left (so quite a queue needed) if anything choosing this option reduces the congestion slightly. Not sure if I'd do similar on a small roundabout but then I don't regularly encounter any on which this tactic would benefit.
