History
The constituency was created in 1918 when the two-seat Portsmouth constituency was split into three divisions: Central, North and [Portsmouth Portsmouth South (UK Parliament constituency)|South (UK Parliament constituency)|South].It was abolished for the 1950 general election and largely replaced by a new Portsmouth West constituency as the axis of division changed, but was re-established for the February 1974 general election.
Constituency profile
This urban seat is of average affluence and incomes, with relatively low unemployment compared to the national average measured at the end of 2012 at 3.8% as opposed to 2.3% average across the region.Compared to Portsmouth South, it has a lower proportion of public sector workers, students and ethnic minorities. This explains the divergence between the two Portsmouth seats in voting patterns. The seat is currently in Labour hands, but very narrowly, with the former Conservative MP and leadership candidate Penny Mordaunt commanding a large personal following.
The seat has been one of the most long-standing bellwethers, having that status since its creation in February 1974 ; only the Dartford constituency have a longer-standing status, which has been a bellwether since 1964.
