Except do the left generally want lockdowns now, in summer 2022?
Lockdowns are one cause of the current economic problems, so it wouldn't look good for any left-wing politician to deny they had side effects.
I suspect that harsher restrictions (never mind lockdowns) will be very unpopular in the next few months (with all the other problems) so any politician of any sense, left or right, would probably be wise not to advocate compulsory 10-day self-isolation, testing to travel abroad or to attend nightclubs or public events, and the like.
