Size matters? The role of small parties in the UK’s two-party system

Due to the nature of the UK’s ‘First Past the Post’ (FPTP) system, it has historically been hard for new, smaller parties to gain political leverage. This has been seen by the domination of both the Conservatives and Labour Party in general elections, with smaller parties very rarely wielding political power. However, in recent years, this norm has had a transformative shift. The Hung Parliament in 2010, allowed the smaller Party, the Liberal Democrats to gain power in a coalition and even more recently with the emergence of parties such as Reform UK and the Reclaim Party which have received much attention, as a threat
to the Conservatives
. This seismic shift is a recent phenomenon, but why? What has led to this threat to the traditional two-party system?

UKIP has been staunchly argued to be one of the core reasons for the United Kingdom voted to leave the EU in 2016. Their influence was seen to be significant as, ‘classically, UKIP took an issue neither party has addressed effectively — immigration — and used it to build a substantial third-party challenge.’ (Parker, Vox, 2016) Although historically a Party that held little political power and influence, this all changed once UKIP took a step towards being the Party that defined ‘anti-immigration’ and placed the blame on the EU. As a result, the leader, Nigel Farage, became the face of Brexit, during the years of the referendum. UKIP and Farage’s success, ‘benefited from the groundwork laid by UKIP over the past several election cycles in local council elections — increasingly, elections won at the expense of Labour.’ (Parker, Vox, 2016) This sudden shift, led to the eventual pressure on the larger parties, mainly the Conservatives who promised a referendum on membership of the EU in the 2015 General Election, in which the UK did leave. This showed how much leverage UKIP really had over the political system at this time and is an example of a smaller party gaining huge influence, on such monumental political decisions without being elected.

Additionally, smaller parties have gained more influence in recent years with the example of the Liberal Democrats gaining political power after the 2010 election. Although being the third-largest party at general elections, they have had little power over those years and even though have had a
decent vote share over the years
, due to the electoral system this was not reflected in tangible power. However, there was a shift in this norm in 2010. The hung parliament  led to the Liberal Democrats going into coalition with the Conservatives, therefore holding power and being able to enact certain policies. This is another argument that smaller parties have in recent decades gained more power than they had previously through different means. However, the Liberal Democrats’ participation in the coalition government was seen to be their downfall with the then Foreign Secretary, William Hague, reportedly told his wife, ‘I think I’ve just killed the Liberal Democrats.’ (Cutts & Russell, 2015, p.70) Although this ended up being true, with their popularity rapidly decreasing in years after the 2015 election, it showed that smaller parties do have a chance in the usually infamous two-party system.

However, although these examples show smaller parties having a level of success in pushing their agenda and holding influence, this view can be challenged. With historical examples such as the Social Democrat Party. Formed by MPs from the Labour Party, who defected due to differing opinions from Michael Foot, the Labour leader. The SDP were, ‘openly of the desirability of ‘breaking the mould’ of British politics by the formation of a new centre party.’ (Bochel & Denver, 1984, p. 386) Despite this seemingly exciting new party, this optimism mounted into little success. The party only reached significant success when eventually morphed into the Liberal Democrats.

A similar scenario played out in 2019 when the formation of Change UK occurred. Consisting of initially Labour MPs and soon after Conservatives. With its main objective to have a second referendum on EU membership, the party reached no success. This was seen when all MPs lost their seats in the 2019 General election, leading to the formal deregistering from the electoral commission in summer 2020. Both these examples of the SDP and Change UK, show breakaway parties are unsuccessful in the British political system, mainly due to the electoral system making it hard for new, smaller parties and therefore challenge the status quo.

Overall, although there are many examples of newly formed, smaller parties historically and up to the present finding it hard to gain much traction within the political system, this could be shifting especially in recent years since the Brexit referendum. this can be seen with UKIP’s influence and even more recently new parties like Reform UK have been a seeming threat to the Conservatives seen in recent by-elections with them taking a significant chunk of the vote share and therefore could be evidence of the electoral system changing.
