What this dot point is asking
Edexcel wants you to know the origins and historical development of the Conservative, Labour and Liberal Democrat parties and how this shapes their current policies on the economy, law and order, welfare and foreign affairs, the importance of minor parties, the development of a multi-party system and its implications, and the factors that explain party success or failure, including the influence of the media.
The established parties
The Conservative Party
The Conservatives evolved from the early nineteenth-century Tory Party. The One Nation tradition, associated with Disraeli, accepts a degree of state intervention and social obligation to hold society together. From the late 1970s the New Right (Thatcherism) combined neo-liberal free-market economics (privatisation, deregulation, lower taxes) with neo-conservative social authoritarianism (tough on law and order, traditional values). Current policy leans toward lower taxes and a smaller state, firm law and order, conditional welfare and a sovereigntist foreign policy, though the balance between One Nation and New Right shifts over time.
The Labour Party
Labour grew from the trade union movement and socialist societies around 1900. Old Labour stood for social democracy: nationalisation (the original Clause IV), strong trade unions, redistribution and a large welfare state. New Labour under Blair and Brown (from 1994) embraced the Third Way, accepting the market and rewriting Clause IV while investing in public services. Since 2010 the party has moved between a more left-wing programme under Corbyn and a return to the centre under Starmer. Current themes include public investment, workers' rights and economic stability.
The Liberal Democrats
The Liberal Democrats were formed in 1988 from the merger of the Liberal Party and the Social Democratic Party. They combine economic liberalism (free markets with a safety net) and social liberalism (civil liberties, constitutional reform, internationalism, environmentalism). They governed in coalition with the Conservatives from 2010 to 2015, which damaged them electorally, before recovering ground.
Minor parties and the party system
The specification requires knowledge of two minor parties. Useful choices include the Scottish National Party (social-democratic, pro-independence, dominant in Scotland), Reform UK (right-wing, anti-immigration, low-tax), the Green Party (environmentalist, left-wing) and Plaid Cymru (Welsh nationalist). Minor parties shape the agenda, win seats in devolved bodies and occasionally at Westminster, and can hold the balance of power.
Is the UK a multi-party system?
Yes, in votes and the devolved nations. Smaller parties win a large and rising share of the national vote; the SNP dominates Scotland; the devolved parliaments use proportional systems (AMS in Scotland and Wales, STV in Northern Ireland) that routinely produce multi-party and coalition government; and the 2010 to 2015 coalition showed multi-party government even at Westminster.
No, in Westminster seats and government. First-past-the-post squeezes smaller parties, so the Conservatives and Labour still take the overwhelming majority of Commons seats and almost always form single-party governments. On this view Westminster remains a two-party system with a multi-party periphery.
Factors in party success and failure
Party success depends on leadership and unity (Blair's united New Labour won; a divided Conservative Party in the mid-1990s lost), policy and the political context (offering popular policies at the right moment), the electoral system (first-past-the-post rewards large, geographically concentrated parties), and the media (supportive press and effective social-media campaigning). The debate over media influence (whether papers shape or merely reflect opinion) links directly to the next area on voting behaviour.
Examples in context
- New Labour 1997, a united, well-led party winning a landslide, illustrating the leadership and unity factor.
- The 2010 to 2015 coalition, the clearest case of multi-party government at Westminster.
- SNP dominance of Scotland, evidence of a genuine multi-party system in a devolved nation.
- Reform UK and the Greens, minor parties winning significant vote shares but few Commons seats under first-past-the-post.

A Section A 30-mark essay (shown as 20) on AO1, AO2 and AO3. Build two-sided arguments around how many parties realistically share power.
For a multi-party system: the SNP dominates Scotland; Plaid Cymru, the Liberal Democrats, Reform UK, the Greens and the DUP and Sinn Fein hold seats; devolved bodies use proportional systems that produce multi-party and coalition government; the 2010 to 2015 coalition showed multi-party government at Westminster.
Against: Westminster remains effectively a two-party system because first-past-the-post squeezes smaller parties, so the Conservatives and Labour still take the overwhelming majority of seats and form single-party governments; minor parties win votes but few seats.
A Level 5 answer judges that the UK is multi-party in votes and in the devolved nations but remains two-party in Westminster seats and government, the key distinction.
Edexcel 202220 marksExplain and analyse three factors that explain the electoral success or failure of a political party. Edexcel 9-mark 'explain and analyse' style; develop each point.Show worked answer →
An "explain and analyse three" question is AO1 and AO2 only, no evaluation. Choose three distinct factors and develop each.
One: leadership and unity, where a credible, united leadership (Blair's New Labour 1997) wins and a divided one (the Conservatives in the mid-1990s) loses. Two: party policy and the political context, where a party offering popular policies at the right moment succeeds. Three: the electoral system and the media, where first-past-the-post and supportive press coverage favour the larger parties and squeeze minor ones.
Markers reward three accurate, distinct factors, each developed with an example and a clear analytical link to success or failure.
