The seat is a borough constituency (for the purposes of type of returning officer and election expenses). As with all current constituencies it elects one Member of Parliament (MP) by the first past the post system.

2010-2024: The wards which make up this seat include Compton, Devonport, Stonehouse, Drake (which includes the University and Mutley), Efford and Lipson, Peverell, St Peter and the Waterfront, Stoke, and Sutton and Mount Gould.

The constituency is entirely within the boundaries of the City of Plymouth, and includes the city centre.

2024-present: The composition of the constituency from the 2024 United Kingdom general election will be reduced slightly in order to bring the electorate within the permitted range, by removing north-western parts of the City of Plymouth ward of Peverell - namely polling districts KC and KD - to be transferred to Plymouth Moor View.

History

History of boundaries

The 2007 review by the Boundary Commission for England recommended the creation of this seat and Plymouth Moor View, which was duly approved by Parliament. It is largely based on the former Plymouth Sutton. To this is added smaller parts of the former Plymouth Devonport seat.

History of results

This constituency was won on creation in 2010 by a Conservative, Oliver Colvile. In 2015, against opinion polls for losing, Colvile held it (but narrowly) over the Labour candidate Luke Pollard. The 2015 result gave the seat the 7th most marginal majority of the Conservative Party's 331 seats by percentage of majority.

In 2017, Pollard defeated Colvile to gain the seat with a majority of 6,807; originally, the majority was declared as 6,002, but a spreadsheet error meant the votes from the Efford and Lipson wards were not included in the declaration on the night of the count. Additionally about 35,000 postal voters received two polling cards, and some postal votes were not sent out.
