Turns up, Doctor Rowe fairly welcomed by sovereign - the first citizen? (4,5)

I believe the answer is:

lord mayor

I'm a little stuck... Click here to teach me more about this clue!

'first citizen?' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for lord mayor that I've seen before include "city position" , "Local dignitary" , "magistrate" , "head for city" , "VIP in London, perhaps" .)

I've seen this clue in the Irish Times.
