The first MP in the re-established constituency was Christopher Brocklebank-Fowler, who had gained King's Lynn, largely a bellwether seat, from one of Harold Wilson's government colleagues in the Labour Party.

Therefore, at the following election, Brocklebank-Fowler chose to contest another seat[n 3] and Labour's candidate regained second place in this constituency, almost doubling their share of the vote.

The 2010 election saw political party infighting when the Labour candidate for North West Norfolk, Manish Sood[n 4][2] stated in an interview with the local newspaper Lynn News that Gordon Brown was "the worst prime minister we have had in this country".

[3] He ended up finishing third, behind Bellingham and the Liberal Democrat candidate William Summers, whose party received their best ever result in the constituency,[4] with an 18.3% swing from Labour to the others.

Bellingham's majority fell slightly in 2015, but he retained the seat in the 2017 general election with 60% of the vote, having been knighted in the New Year's honours list of 2016.

Contrasted with this is the bulk of the area: the tourist resort Hunstanton, retail, military, public sector and commercial activity of Kings Lynn and the royal estate at Sandringham, along with many small villages and more than 50% undulating cultivated farmland — incomes and types of dwelling are close to the national average.
