The present constituency follows the boundaries of the old Borough of Great Grimsby, which was abolished when the former county of Humberside was divided into four unitary authorities in 1996. From the 2010 general election new boundaries took effect, but the Boundary Commission's review led only to minimal changes, aligning the constituency boundaries with present ward boundaries so the seat still has electoral wards:
East Marsh, Freshney, Heneage, Park, Scartho, South, West Marsh and Yarborough.
The constituency has been represented since the first House of Commons was assembled in the Model Parliament of 1295, and it elected two MPs until 1832. Great Grimsby was established as a parliamentary borough in 1295, sending two burgesses, and has been continuously represented ever since. The town of Grimsby in Lincolnshire, a market town, fishing port and seaport.
Freemen of the town had the right to vote, provided they were resident and paying scot and lot; in 1831 this amounted to just under 400 voters. The town corporation bestowed this status, as today, rarely on those bringing acclaim to the place, but it was routinely acquired through apprenticeship in the guilds and by inheritance; in Great Grimsby, unusually, the husband of a freeman's daughter or widow acquired the freedom.[n 4]
In 1831, when the Reform Bill was being discussed in Parliament, the wives and daughters of the Great Grimsby freemen petitioned the House of Lords to retain their rights to pass on the vote to their future husbands and children. However, their concern to retain these rights may not have been rooted in any their family desiring to help choose the borough's MPs as a vote in Great Grimsby was a valuable commodity in a more mercenary sense, and the contemporary polemicist Oldfield considered that "This borough stands second to none in the history of corruption." At the start of the 18th century it was noted[by whom?] that Grimsby's "freemen did enter into treaties with several gentlemen in London, for sale of the choice of burgess to such as would give the most money". In 1701, the House of Commons overturned the election of one of Great Grimsby's MPs, William Cotesworth, for bribery and sent him to the Tower of London and temporarily suspended the borough's right to representation. Almost every election in Great Grimsby at this period was followed by a petition from defeated candidates alleging bribery, although that of 1701 seems to have been the only one which was acted upon.
Great Grimsby, like most boroughs except for the very largest, recognised a "patron" who could generally exercise influence over the choice of its MPs; at the time of the Great Reform Act of 1832, this was Lord Yarborough. However, the extent of the patron's power was limited in Great Grimsby, and the voters were quite prepared (at a price) to defy his advice. The patron could strengthen his position by providing employment to the freemen, as could his rivals. Jupp quotes two letters, one of 1818 and one of 1819, in which local agents advise the Tennyson family how best to do this in Grimsby so as to encroach on Lord Yarborough's influence:
"Build upon every spot of vacant ground you are possessed of... Thus you would give employment to a great number of freemen... Let Mr Heneage's estates[n 5] be divided into fields of four or six acres; and let these, together with your own estates be placed in the hands of freemen to whom they would be an object of importance. Provide, if possible, small farms for the sons of Lord Yarbro's tenants."
On a less extravagant level, it is recorded that after Charles Tennyson was first elected in 1818 he presented a bottle of wine to each of the fathers of 92 local children about to be christened.
The General Election of 1831 in Grimsby was as notorious as in some of the rotten boroughs, the local Tories being accused of using a revenuecutter lying in the Humber to ply the Whig voters with drink and prevent them getting to the polls; the fact of the outcome standing led to a nationally well-known action by John Shelley for libel.
In 1831, the population of the borough was 4,008, and contained 784 houses. The Boundary Act in concert with the Reform Act enlarged the borough to include eight neighbouring parishes[n 6], brought the population up to 6,413 with 1,365 houses but the landed property aspect to the franchise was not reformed so this increased the electorate only to 656 so Great Grimsby lost one of its two seats. However, Grimsby's population and housing continued to grow and, unlike most of the boroughs that lost one seat in 1832 it has retained its existence, without taking up large swathes of the county.
The constituency underwent further significant boundary change in 1918 and 1950. In 1918, parishes that had joined, (Bradley, Great Coates, Little Coates, Laceby, Waltham, Weelsby and the adjoining neighbourhood/parish of Scartho) were detached to join Louth county constituency, and the seat [n 7] consisted of the county borough of Grimsby and the urban district (later borough) of Cleethorpes. In 1950, Cleethorpes was moved into the Louth county division, leaving the borough once more Grimsby alone. More recent boundary changes have only been adjustments to conform to changes at local government level.
Since the 1950 boundary changes that removed Cleethorpes,[n 8] results since 1945 have returned Labour MPs, many suggesting a safe seat and others with a marginal majority presenting the picture of a Labour-held marginal seat.
^On petition, the Commons resolved that William Cotesworth "has been notoriously guilty of bribery and other indirect practices", that he had not been duly elected and that his offences he should be committed as a prisoner to the Tower of London. They also resolved that no new writ for Great Grimsby should be issued for the remainder of the session, leaving the seat vacant
^On petition, which accused both Loft and Boucherett of bribery and treating, the result of the 1802 election was overturned. The committee amended the result of the voting, so that Loft who had been placed first was placed third, and declared Mellish duly elected in Loft's place.
