Most of this zone was in
Finchley (abolished), created in 1918, most famously represented by former
Conservative Prime Minister Margaret Thatcher from 1959 to 1992; reshaping meant that she never re-won as large a majority as in
1959, and was re-elected by a 10 per cent margin in 1974. She nonetheless won 8,000 and 9,000 majorities, 20 per cent margins, at the three
general elections throughout her premiership. Since the nominal result at the
1992 general election, and officially from its creation, the seat has been a national
bellwether. The 2015 result gave the seat the 65th-most marginal majority of the Conservative Party's 331 seats by percentage of majority. The 2019 result saw
Labour's share of the vote decline by 19.6% as the party dropped to third place. This was the eighth-worst decline among the 630 Labour candidates. The
Liberal Democrats, whose candidate was
Luciana Berger, the former Labour MP for
Liverpool Wavertree, came second in the seat for the first time, increasing their vote share by 25.3%, the third-largest increase of their candidates. They were partly helped by the
Green Party's choice to stand aside locally via the
Unite to Remain electoral pact. Despite the Conservative share of the vote going down 3%, their majority quadrupled from 2017. At the
2024 general election, Labour regained the seat, having recovered its vote at the expense of the Liberal Democrats with a 22.5% swing between the two parties. ==Constituency profile==
