That's only available to those with an undergraduate degree from Cambridge who, subsequent to their undergraduate degree, publish work worthy of a Ph.D. and pass a viva.
I'm not sure how common a route ot Ph.D. it is (I never heard of it before), but it sounds like an anachronistic extension of the MA's Oxbridge graduates feel entitled to.
Correct. It is generally an exceptionally rare path to a PhD, but the door is open. I believe I saw the statement that this particular program has granted ~100 degrees over its life compared to ~15000 PhDs from Cambridge.
