Deputy-elect Doublet had been backed by outgoing Deputy Tracey Vallois, who had moved out to St John.
She is joined by Deputy Kevin Lewis, who has spent the last three years as Transport Minister. The Deputy bucks the trend of people with that ministerial poisoned chalice – both of the previous ministers lost their seats after a term in charge at South Hill.
The district saw a turnout of 33.97%, and there were 13 spoiled papers.
The vote was as follows: Deputy Kevin Lewis (727), Louise Doublet (632) and Maureen Morgan (285).
