Portsmouth (UK Parliament constituency)
Portsmouth was a borough constituency based upon the borough of Portsmouth in Hampshire. It returned two members of parliament (MPs) to the House of Commons of the Parliament of the United Kingdom, elected by the bloc vote system. History 

The constituency first elected MPs in 1295. It was abolished at the 1918 general election, when the Representation of the People Act 1918 divided it into three new constituencies; Portsmouth North, Portsmouth South and Portsmouth Central. According to Namier and Brooke in The House of Commons 1754–1790, the right of election was in the freemen of the borough who numbered about 100. The town was known as an Admiralty borough and at least one MP was usually an Admiral. The Earl of Sandwich was First Lord of the Admiralty from 1771 to 1782. He imposed tighter Admiralty control over the borough. This change of policy led to an independent element of the local Council supporting challengers to the Admiralty candidates between 1774 and 1780. When party politics re-emerged in the late 18th and early 19th centuries, Portsmouth was a predominantly Whig constituency. It only once elected a Tory Member of Parliament between 1790 and 1832. The Reform Act 1832 considerably expanded the electorate of the borough. The freemen retained their ancient right franchise, but were outnumbered by the new occupier voters amongst the 1,295 electors registered in 1832. As a result of the expanded electorate the borough became more competitive. Contested elections became the norm rather than the exception, as they had been before the Reform Act. Candidates with naval connections continued to be frequent in Portsmouth, after the Reform Act. The borough developed into a marginal constituency, particularly in the last half century of its existence. Boundaries
The parliamentary borough of Portsmouth was (as the area remains in the 21st century) a major seaport and naval base on the south coast of England. It is situated in the county of Hampshire. From the 1885 general election until the dissolution before the 1918 election the constituency was surrounded (on the landward side) by the Fareham seat. Members of Parliament

Notes

Election notes
The bloc vote electoral system was used in two seat elections and first past the post for single member by-elections. Each voter had up to as many votes as there were seats to be filled. Votes had to be cast by a spoken declaration, in public, at the hustings (until the secret ballot was introduced in 1872). Note on percentage change calculations: Where there was only one candidate of a party in successive elections, for the same number of seats, change is calculated on the party percentage vote. Where there was more than one candidate, in one or both successive elections for the same number of seats, then change is calculated on the individual percentage vote. Note on sources: The information for the election results given below is taken from Sedgwick 1715–1754, Namier and Brooke 1754–1790, Stooks Smith 1790–1832 and from Craig thereafter. Where Stooks Smith gives additional information or differs from the other sources this is indicated in a note after the result. Election results 1715–1800
