Electors cast a single vote by placing a cross on the ballot paper
The one with the most wins
A person does not necessarily need more to get 50%
Whichever party has a majority of the MPs can form a government
Where it is used
Elections to the Westminster Parliament (HoC)
There are 650 constituencies
Also used in local government elections
Advantages
It is easy to understand
FPTP tends to return strong and stable governments which can
fulfil there manifesto pledges. They usually have to enter into
coalition governments. As a result the governing party can be
held directly accountable for its policies at the next general
election. (2010 being the exception)
Tends to be a strong link between the MP and their
constituents. Only one representative so people
are more likely to know who their representative is
It builds strong levels accountability. Voters can easily track the
work of their local MP and can hold them to account by kicking
them out of office next time
Has been very successful at keeping extremist parties out of influence in
British politics since parties such as the BNP have generally lacked the depth
of support necessary to win a constituency
Disadvantages
FPTP is particularly controversial because its critics argue that it does not fairly
translate votes into seats. Two main parties win more seats than their votes
merit. The lead party gaining a 'winner's bonus'
Minority parties with thinly spread support are under-represented
(UKIP in 2015 with over 3.8 million votes but only one seat)
Creates 'electoral deserts' - parts of the country where the
party has little or no representation
A party can actually win the most votes, but
receive fewer seats than its main rival and
hence lose the election. (In 1951 the Tories
won more seats than labour with less votes In
1974 the opposite happened)
Winning candidates do not need to secure a majority of the
votes cast in their constituency. MPs elected on minority
mandates
Most MPs have less than half of the voted in their constituencies. In 2015 331 of 650 MPs
were elected without an absolute majority
FPTP does not promote the idea of 'one person, one vote'. A vote in a small
constituency is more likely to influence the outcome than a vote in a larger one
