What this dot point is asking

You need to explain the functions of UK political parties, the ideas and internal divisions of the Conservative and Labour parties, the role of minor and third parties, party funding and the debate over its reform, and whether the UK party system is healthy. The CCEA AS 2 paper rewards precise knowledge of how parties work and a balanced judgement on the party system.

The functions of parties

Parties perform several functions that hold the political system together:

  • Representation. They aggregate the many interests and opinions of society into a small number of broad, coherent programmes.
  • Participation and mobilisation. They give citizens a way to participate, by voting, joining, campaigning or standing, and they mobilise turnout.
  • Political recruitment. They select, train and promote candidates, producing the personnel of government and opposition.
  • Policy formulation. They develop manifestos, offering voters a structured choice between programmes and giving the winner a mandate.
  • Government and accountability. They organise government and a credible opposition, making power accountable at the next election.

The Conservative Party

The Conservative Party is the main centre-right party. Its traditional ideas include support for free markets and enterprise, a strong state on law, order and defence, gradual reform rather than radical change, and the Union and national institutions. In practice it contains lasting internal divisions: between free-market and more interventionist wings, between social liberals and social conservatives, and, most damagingly in recent decades, over the UK's relationship with Europe, which split the party repeatedly and shaped the Brexit era. These divisions make managing the party a recurring challenge for its leaders.

The Labour Party

The Labour Party is the main centre-left party, founded to represent the working class and trade unions. Its traditional ideas include support for public services (above all the NHS), redistribution and social justice, workers' rights and a larger role for the state. It has a long-standing internal division between its social-democratic wing (accepting the market economy and seeking to reform it, as under "New Labour") and its more socialist or left wing (favouring greater public ownership and redistribution). The balance between these wings has swung back and forth and is central to understanding Labour's strategy and electability.

Minor and third parties

Several smaller parties shape UK politics despite winning few Westminster seats under FPTP:

  • Liberal Democrats. The main centre, socially liberal and pro-European party; junior partner in the 2010 to 2015 coalition.
  • Scottish National Party (SNP). The dominant party in Scotland, seeking Scottish independence; a major bloc at Westminster.
  • Reform UK. A right-wing, populist party (successor to the Brexit Party), drawing votes from the Conservatives.
  • Greens and Plaid Cymru. Environmental and Welsh-nationalist parties respectively, stronger in the devolved bodies and local government.

These parties influence the agenda, can win significant vote shares, and do far better under the proportional systems used in the devolved bodies than under Westminster's FPTP.

Party funding and reform

Reform proposals include a cap on individual donations, tighter rules on trade union funding, greater transparency, and state funding of parties to reduce dependence on private money. Critics of state funding argue it forces taxpayers to fund parties they oppose and entrenches existing parties; supporters argue it would clean up politics and level the playing field. The debate remains unresolved, and the Electoral Commission regulates donations and spending.

Examples in context

A model AS paragraph on the party system might read: "Whether the UK is still a two-party system depends on where you look. At Westminster the answer is broadly yes: the Conservatives and Labour win the overwhelming majority of seats and alternate in single-party government, an outcome that first-past-the-post actively manufactures by penalising parties with dispersed support. Yet beneath the seat totals the picture is increasingly multi-party: the combined vote share of the two main parties has fallen over the long run, the SNP dominates Scotland, and parties such as Reform and the Greens command significant support. The judgement, therefore, is that the UK has a two-party system at Westminster sustained by the electoral system, layered over an electorate and a set of devolved arenas that are genuinely multi-party." This distinguishes seats from votes and reaches a verdict.

Q3. To what extent are the UK's main parties internally divided? [24 marks]

  • Cue. Weigh the Conservative divisions over Europe and the state and Labour's social-democratic versus socialist split against the discipline parties maintain in office. Reach a substantiated judgement.

A 12-mark AS 2 explain question. Identify several functions and explain
how parties perform each.

Representation and participation. Parties aggregate interests and opinions
into broad programmes and give citizens a way to participate, join and
stand for office.

Recruitment and government. Parties select and train candidates, recruit
the political class and provide the personnel of government and
opposition.

Policy formulation and electoral choice. Parties develop manifestos that
offer voters a coherent choice of programmes, and the governing party
delivers a mandate. A top answer explains several functions clearly.

CCEA AS 2022To what extent is the UK party system still a two-party system? [24 marks]
Show worked answer →

A 24-mark AS 2 evaluation question. Weigh continuing two-party dominance
against multi-party features.

Still two-party. The Conservatives and Labour win the vast majority of
Commons seats, alternate in government, and FPTP entrenches their
dominance, so government is almost always single-party.

More multi-party. Vote share for the two has fallen over time, third
parties (Liberal Democrats, the SNP, Reform, Greens) win significant
votes and, in the SNP's case, many seats, and the devolved bodies have
genuinely multi-party systems.

A strong answer judges that Westminster remains effectively two-party
because of FPTP, while the underlying electorate and the devolved arenas
are increasingly multi-party, then reaches a verdict.
