Southampton (UK Parliament constituency)

Southampton was a parliamentary constituency which was represented in the English and after 1707 British House of Commons.

Centred on the town of Southampton, it returned two members of parliament (MPs) from 1295 until it was abolished for the 1950 general election.

The election was declared void on petition on 6 May 1842, due to bribery by Bruce and Martyn's agents, and a writ for a by-election was not moved until 1 August 1842.

Cockburn resigned after being appointed a Chief Justice of the Court of Common Pleas, causing a by-election.

Butt resigned after being appointed a Judge of the Probate, Divorce and Admiralty division of the High Court of Justice, causing a by-election.
