Labour has enjoyed success here for 60 years and Austin Mitchell, Great Grimsby's sitting MP since the 1977 death of then Foreign Secretary Anthony Crosland, currently has as healthy a majority as at any time in this seat's recent history.
There have been no boundary changes to this constituency in recent times, but local politics have been drastically altered by the abolition of the county of Humberside. That has meant that local elections are no longer held in the borough of Great Grimsby, but in the new unitary authority of North East Lincolnshire.
Grimsby is dominated by fishing and the food industry, with its colleges enjoying a world-wide reputation for their food and refrigeration courses. It is also one of the largest container ports in the country, but is not dominated by its docks, and the town has its attractive areas with wide, tree-lined roads leading to the centre.
The chemical industry has been developed here in recent years, and trade, generally with Scandinavian countries, has been boosted by the construction of the A180(M) link road. The seat is home to the highest proportions of both part-time and partly-skilled workers in England and Wales, but unemployment is also high.
