Traditionally a two party system
Labour and conservative dominate the HOC- due to FPTP
2017 GE- Labour and Conservative won 82% of the vote- highest vote share since 1979
The Conservatives and Labour have traditionally covered a broad aspect of policy areas- trusted with running government-have expertise
However- In 2017 The Conservatives had to rely on the DUP anyway
In 2019- The Conservative and Labour vote share decreased to 75% with just over 24% of people voting for minority parties
Electoral Systems
FPTP- disproportionate and unrepresentative and therefore Minor parties are significantly disadvantaged- preventing minor parties from gaining significant seats and influence in parliament
Winners bonus- advantage winning party- 2019- Conservatives won 56.2% of seats with only a minority of the vote share 43.6%
Minor parties may struggle to gain geographical concentrated support needed under FPTP- Green Party in 2015 won 1 million votes but only one seat
FPTP leads to people voting tactically
However:
Proportional voting systems in devolved bodies have allowed for an increase in minority party representation
Independence Parties such as the SNP have been able to take advantage of geographical location and in 2015 won 56/59 seats
Rise in independence parties has led gov to allow independence referendums
Influence on Policy
Elective dictatorship- little constraints on the executive
Due to FPTP usually delivering a strong majority and the whip/patronage system in place- government is likely to guarantee support on legislation- this means minor parties have little influence in legislation and will struggle to contest it
2019-21- 92% of bills passed were government bills or public bills- minor parties will introduce bills for coverage and exposure to issue
Public BIll Committees=heavily whipped and composed of majority parties- opposition are unlikely to have amendments accepted
However- If the minor parties put pressure on government through people, they are still able to significantly influence legislation
2015- UKIP- came third with 12.6% of vote- demonstrated to government that people wanted something done about Brexit, threatened the governments stability- UKIPS vote share fell to 1.8% in 2017
Conservative-Liberal Democrat coalition from 2010-2015- Cameron had to accept a referendum on AV and had to give up 5 positions in the cabinet to the lib Dems
In conclusion:
Despite minor parties not having significant number of seats in the HOC- their influence can be demonstrated elsewhere through devolved regions and their impact on policy.
