Indicating On Roundabouts

[EcclesCake]

Is it no longer required to indicate when entering and exiting roundabouts?

A stretch of road I drive almost daily is littered with full size roundabouts and on numerous occasions I have followed driving school cars with a student at the wheel and they never indicate.

Indicating enables traffic to proceed much more smoothly hence my baffledom when there is no indicating.

If you are making a turn you should indicate
what about the pedestrians who are waiting to cross the road
if you turn a corner without using your indicators you are a bad driver.
