Category: Semi-marginal Conservative seat
Geography: South East, Hampshire. Part of Portsmouth council area.
Main population centres: Portsmouth.
Profile: Portsmouth is a densely populated city on the south coast, technically situated on a island though the numerous causeways mean it is effectively a peninsula. It has a strong naval history as the home of the largest Royal Navy base, with defence the main local employer. Portsmouth South contains the main naval base, the docks and shipyards and many of the post war council estates like Buckland and Portsea. It also contains Portsmouth University, and is the more student heavy of the two Portsmouth seats.
Politics: Historically a Conservative seat, Portsmouth South was first won by Mike Hancock as the SDP candidate in the 1984 by-election following the death of Bonnor Pink. Hancock was not able to hold it at the subsequent general election, but continued to fight the seat, becoming leader of Portsmouth council in 1989, unsuccessfully standing again in 1992 and finally regaining the seat in 1997. He remained the MP until 2015 but ended his career in disgrace, suspended from the Liberal Democrats and standing against them as an Independent after allegations he had made inappropriate sexual approaches to a constituent. The Conservatives regained the seat.

*There were boundary changes after 2005













‘This result has been little commented on but was in historical context was at least as remarakable those in Kensington and Canterbury’
Totally agree – big win for Labour here
It was quite extraordinary this result.
I think the same has happened in Scotland, but this is surely the only English constituency to be won by three different parties in 2010, 2015, and 2017.
Looking back over the constituency pages a few years ago , there was a great deal of speculation of Mike Hancock having to resign, and a shock UKIP gain here in a by-election.
There’s a chance that might happen in Southport too, assuming Labour support remains strong (or improves).
2015 – Lib Dem, 2017 – Conservative, next election – Labour?
Falmouth & Camborne (and successors) is the obvious example of a constituency held by 3 parties in 3 elections: 2001 – Labour, 2005 – Lib Dem, 2010 – Conservative
Cllr Julie Bird (Fratton ward) has defected to the Conservatives here.
“My move from UKIP to Independent to the Conservatives is a natural one.”
Penny Mordaunt is new defence sec.
She will remain Women and Equality Minster (perhaps that is an hint a Man will replace her at DFID.)
Wrong thread.
This could be one of the more interesting seats on election night.
