I would guess that the temporary signs are there pending the
installation of a permanent up arrow, which the Traffic Signs Manual
gives as the correct sign for use in this situation when the junction is
controlled by lights.

That's pretty strange, though. The traffic light is new.

Which makes it all the more likely that it is a temporary cock-up.

More data: the brand new layout at Palmers Green has separate lanes for
turning left and right off the North Circular, and the same thing has
been done, i.e the going forward lanes have no signage apart from the
green arrow (and lane markings), and the turning right lanes have a no
u-turn sign but no forced right sign apart from the green arrow. So it's
not a temporary cock up but a systemic failure IMO.
