There were four principal authority by-elections across England on Thursday 20 August. Labour were defending two seats, Reform UK were defending one and there was one vacancy in Huntingdonshire where Reform had won one of the ward’s three seats at the May elections.

The Liberal Democrats were defending no seats this week, but produced the standout result of the night by gaining St Neots Eynesbury from Reform UK with a commanding swing of almost 30 percentage points. Elsewhere, Labour regained a Reform seat in Barnsley, Reform gained from Labour in Carlisle’s Harraby South, and Nottingham’s crowded six-way contest demonstrated how fragmented local politics has become in parts of the country.

Huntingdonshire DC, St Neots Eynesbury

The headline result of the week came in St Neots Eynesbury, where the Liberal Democrats overturned a Reform UK gain made only three months ago. In May’s district elections, Reform had won two of the ward’s three seats after the collapse of the long-standing St Neots Independent Group representation, while the Liberal Democrats finished third. This by-election represented an immediate opportunity to test Reform’s breakthrough here.

The wider political context made the contest even more significant. At the 2026 elections, the party won 20 seats to become the largest group on the council, overtaking the Conservatives, but remained short of an overall majority on the 52-seat authority. Since then, the minority administration has faced additional pressure after the Green Party just this week left the governing arrangement, leaving the Liberal Democrat and Independent administration operating on a knife edge. This gain lifts the administration’s combined strength to 26 seats, exactly half the council, which marginally strengthens its position.

St Neots itself has become one of the Liberal Democrats’ strongest parliamentary success stories too. The town sits within the St Neots and Mid Cambridgeshire constituency won by Liberal Democrat MP Ian Sollom in 2024, and Eynesbury has seen significant housing growth over recent decades, creating an electorate that has become increasingly competitive between several parties.

Against that backdrop, Ian Taylor delivered an outstanding victory. His 1,024 votes and 47.9% share represented a remarkable 29.8-point increase on the previous Liberal Democrat performance, while his 377-vote majority over Reform UK sends a powerful signal about the value of sustained local campaigning.

Huge congratulations to Ian Taylor and the team on an exceptional gain that strengthens the Liberal Democrat administration in Huntingdonshire.

Liberal Democrats GAIN from Reform UK

There were two principal authority by-elections across England, Wales and Scotland this week, both held on Thursday 13 August. The Liberal Democrats were not defending either seat, with Reform UK defending Almondbury on Kirklees MBC and Labour defending Honiton St Michael’s on East Devon DC.

It was an excellent night for the Liberal Democrats, with gains in both wards. In Almondbury, Paola Davies returned to the council just three months after losing her seat as Reform swept all three positions at the May local elections. In Honiton St Michael’s, Rhys Wallis took a seat which Labour had won in 2023 but which had subsequently become vacant after its former councillor left the party and sat as an Independent.

Almondbury produced one of the clearest reversals of the May local elections.

The May 2026 election was fought on new boundaries, with three councillors elected and 15 candidates standing. Reform won all three seats, with Gill Floyd, Pip Harvey and Craig Wiles finishing ahead of the three Liberal Democrat candidates. Poala Davies was the strongest-placed Liberal Democrat, on 1,755 votes, while Reform’s three candidates polled between 2,060 and 2,224.

Just weeks later, Wiles resigned from the council, triggering this by-election. That gave Davies the opportunity to return to the ward she had represented previously, and she did so in emphatic fashion. Her 671-vote majority over Reform is particularly striking given that the party had swept the ward only three months earlier. The Liberal Democrat campaign was supported by a grant from ALDC’s Fighting Fund.

The result also provides an important reminder that May’s Reform breakthrough throughout Kirklees was not necessarily a settled realignment. It shows a continued trend of Reform UK not being able to retain seats which they have won recently. It may point to voters not being satisfied with their performance in office, despite big promises and an appeal to the fresh and new when they first stand.

Huge congratulations to Paola Davies and the team on a superb return to the council.

Liberal Democrats: 1,749 (43.9%, +14.5)
Reform UK: 1,078 (27.0%, -10.0)
Conservatives: 528 (13.2%, +4.4)
Green Party: 347 (8.7%, -8.0)
Labour: 181 (4.5%, -3.4)
Independent: 103 (2.6%, new)

Turnout: 29.5%

LIBERAL DEMOCRAT GAIN from REFORM UK

East Devon DC, Honiton St Michael

Honiton St Michael has a particularly interesting recent electoral history. The ward was a three-member ward at the 2023 election, when the Conservatives won one seat, Labour gained one from the Conservatives and the Liberal Party gained one from the Liberal Democrats. Neither the Liberal Democrats nor Reform stood in that election.
