From red wall to King's Speech, UK elections have a vocabulary all their own. Here's what to know

LONDON (AP) — United Kingdom elections have a distinct vocabulary that draws on traditions of parliamentary democracy as well as modern political slogans and spin.

As voters go to the polls Thursday to elect a new government, The Associated Press deciphers some key words and phrases:

Battle bus

Luxury coaches rented by the main political parties to whisk politicians and journalists around the country for campaign visits during the five-week campaign. Labour has a red bus emblazoned with the word “change,” while the Conservatives’ blue bus promises a “clear plan, bold action, secure future.” The centrist Liberal Democrats’ yellow bus has taken leader Ed Davey on a headline-grabbing journey that has involved paddleboarding, rollercoaster-riding, Zumba and bungee-jumping.

Blue wall

A swath of seats in southern England, the wealthiest part of the country, where voters traditionally have supported the Conservative Party, whose traditional color is blue. With the Conservatives trailing in the polls, the centrist Liberal Democrats are targeting these affluent, socially liberal voters and hope to snatch some of the seats. See also: Red Wall.

Brexit

Britain’s departure from the European Union, triggered by a 2016 referendum and completed in 2020, was the country’s most seismic, and divisive, act in decades. Yet it has featured little in the election campaign. The Conservatives don’t want to acknowledge that many of the promised economic benefits haven't materialized. Labour doesn’t want to reopen old wounds or alienate Brexit-backing voters. So Brexit has become something of a political Voldemort — that which mustn't be named.

Coalition government

A rarity in the United Kingdom, a coalition government is one in which two or more political parties divide up ministerial posts, compromise on policies and agree to govern in concert. The Conservative-Liberal Democrat coalition of 2010-2015 was Britain’s first since World War II.

First past the post

Used to describe an electoral system in which the candidate with the highest number of votes in each district wins, even if that person doesn't gain a majority of votes cast. The system tends to favor the two big parties, Conservatives and Labour, which historically have won a majority of seats in Parliament, while taking well under half the votes.

House of Commons

The lower house of Parliament has 650 seats, each representing a district of the U.K. The leader of the party with enough seats to command a majority — either alone or in coalition — becomes prime minister and leads the government.
