William Clouston (politician)

Leadership and political views

Before the European Union membership referendum, Clouston was informed by David Owen that a successor party had been set up after the dissolution of the "continuing SDP" in 1990.^[3] Clouston became the leader of the current Social Democratic Party (SDP) on 24 March 2018, at which point the party had only 78 members, and was later re-elected by the membership in March 2020, with 89 per cent of the votes cast.^[6]

Under his leadership, the party adopted a more eurosceptic and anti-immigration platform.^[7] At the 2019 general election, the party fielded 20 candidates receiving a total of 3,295 votes. Clouston stood in Leeds Central, where he polled 281 votes.^[8] By January 2021, the party's membership had grown to 2,000, according to SDP supporter Rod Liddle.^[9]

At the 2024 general election, the SDP entered an electoral pact with Reform UK, and stood in the largest number of seats since their formation; standing 122 candidates across Great Britain.^[10][11] Clouston himself contested the seat of Hexham, finishing in sixth place with 1,211 votes (2.3%).^[12] Since then, he has criticised the governing Labour Party over its handling of the Chagos deal.^[13]

Clouston has served as the chairman of the parish council in Corbridge, Northumberland.^[14] He was also appointed by Rupert Lowe to the advisory board of Restore Britain, a position he held until Restore was announced as a political party in February 2026.^[11]

2026 Clacton by-election

On 17 July 2026, Clouston announced his candidacy for the 2026 Clacton by-election.^[15][16] He stated that "it’s wrong that the major parties are boycotting this election because the people of Clacton deserve a better choice than Binface or Nigel Farage".^[15] Clouston was the only candidate from an established political party to stand against Farage,^[17] although he received little media coverage and was criticised by Reform UK supporters in light of the SDP's former electoral pact with Reform.^[18]

Former politician Tom Harris wrote of Clouston's candidacy in The Telegraph:

William Clouston ... considers himself the rightful heir to David Owen and Roy Jenkins and believes, with some justification, that his party’s social-democrat, centre-Left economic policies combined with its rejection of modern woke politics would appeal to a large number of disillusioned voters of both the main parties. It’s a pity therefore that this particular circus is likely to leave him and the SDP in little better position than before. The lesson is that an election is the wrong occasion to raise political issues.^[19]

He ultimately placed seventh out of 34 candidates, receiving 256 votes (0.73%) and losing his election deposit.^[20]

Resignation as leader

Clouston resigned as leader of the SDP on 26 August 2026 following the result of the Clacton by-election.^[21] In his resignation letter, he said that it had been "very tough" since the general election, citing the party's lack of national visibility amongst other reasons.^[22] Under his tenure, the SDP had contested more than 400 elections, securing four victories and more than 208,000 votes.^[23]

Molly Kingsley of The Daily Sceptic described the Clacton by-election as a "golden opportunity" for the SDP which was undermined by the media ridiculing the by-election. Kingsley wrote, "it is hard to think of a more valuable or deserving candidate for the Lords".^[24]

In the days following his resignation, political figures including Peter Hitchens, Michael Gove, Toby Young and Dominic Cummings expressed their sadness of his departure from public life.^{[citation needed]} Cummings posted on X saying "A rare decent man in SW1 so it's logical he didn't fit in and has decided to leave and the average quality declines yet further".^{[25][non-primary source needed]}
