Political party membership in the United Kingdom (UK) in 2019

In 2019 the Labour Party was estimated to have over half a million members, by far the most of any political party in the United Kingdom. The next three largest parties in terms of members were the Conservatives, the Scottish National Party and the Liberal Democrats which all had membership numbers that numbered over 100 thousand.

More members but less voters

While the Labour Party clearly had more party members than the Conservative Party, it has also not been in power since 2010 and has struggled to oust successive Tory governments. In the 2019 general election, Labour suffered it's worst result since the 1930s, winning just 203 seats 59 fewer than in 2017, and as a share of the vote, a drop of 7.8 percent.

Labour's strong social media prescence

Despite poor recent election results the Labour Party has an undeniably large following on social media. As of June 2020, they had over 1 million likes on Facebook and over 871 thousand followers on Twitter making them easily the most popular UK political party on both platforms.
