Britain's Super Thursday tests Labour across three nations

Britain's Super Thursday tests Labour across three nations

Rule Changes
By Newzino Staff |

First major electoral test since the 2024 Labour landslide, with Wales debuting a new 96-seat Senedd and Scotland's SNP pursuing a fifth term

Today: Super Thursday polls open across Britain

Overview

Polling stations across England, Scotland, and Wales opened on May 7, 2026, in the largest day of voting Britain has held since Keir Starmer's Labour Party won a landslide general election ten months ago. English voters chose more than 5,000 councillors across 136 authorities, including every seat in all 32 London boroughs. Scotland elected all 129 members of its parliament at Holyrood. Wales, for the first time, elected an expanded 96-member Senedd under a new closed-list proportional system, voting for parties rather than individual candidates.

Why it matters

If Labour collapses as polls suggest, Starmer faces a leadership crisis, Reform UK becomes a governing force, and the union itself comes back into play.

    Badenoch wins Conservative leadership contest after the party's worst general election result.

  4. Eluned Morgan becomes Welsh first minister

    Leadership

    Morgan takes over Welsh Labour and the Welsh government after Vaughan Gething's resignation.

    Keir Starmer's Labour Party wins 411 Commons seats, ending 14 years of Conservative government and forming the baseline being tested today.

  6. Welsh Senedd reform becomes law

Scenarios

1

Labour suffers historic losses; Starmer faces leadership pressure

Discussed by: New Statesman, Yorkshire Post, France 24, pollster Robert Hayward

Labour loses roughly 2,000 of the 2,550 English council seats it is defending and falls to third in Wales. Backbench Labour MPs revive open discussion of a leadership change before the next general election. Starmer survives in the short term but enters a sustained period of internal challenge, with names like Andy Burnham and Wes Streeting cited as alternatives.

2

SNP wins majority and demands second independence referendum

Discussed by: John Swinney, Scotsman, Institute for Government

The SNP outperforms polling and wins 65 or more seats at Holyrood. Swinney declares a renewed mandate and uses the new parliament's first sitting day to seek a section 30 order from Westminster transferring referendum powers. The UK government refuses, triggering a constitutional standoff and a likely Supreme Court case echoing the 2022 ruling that blocked an SNP-only referendum.

3

Plaid-Labour coalition takes power in Wales

Discussed by: YouGov, ITV Cymru Wales, Constitution Unit

Plaid Cymru wins the most seats in the Senedd but falls short of a majority. After negotiations, it forms a coalition or supply-and-confidence arrangement with Welsh Labour, with Rhun ap Iorwerth becoming first minister. The new government revives stalled debates over further devolution of justice and broadcasting powers and opens space for a future independence question.

4

Reform UK becomes a third major force across Britain

Discussed by: Survation, YouGov, BritBrief

Reform UK wins 1,000-plus English council seats, around 19 MSPs, and roughly 34 Senedd seats. The party gains its first formal foothold in devolved politics and becomes the official opposition in either Scotland or Wales. Conservative voters defect in larger numbers, and merger or pact talks between Reform and parts of the Conservative Party intensify ahead of the next general election.

Historical Context

Conservative council collapse (1995)

May 1995

What Happened

Eighteen months before the 1997 general election, John Major's Conservative government suffered devastating local council losses, ceding more than 2,000 seats and losing control of dozens of councils to Labour and the Liberal Democrats. The result confirmed that Tony Blair's Labour was a credible governing alternative.

Outcome

Short Term

Major's authority within the Conservative Party weakened sharply; he triggered a 'put up or shut up' leadership contest in July 1995 to confront critics.

Long Term

The local-election rout was a leading indicator for the 1997 general election landslide, in which Labour won 418 seats and Blair became prime minister.

Why It's Relevant Today

The 2026 contest reverses the polarity but mirrors the dynamic — a governing party is testing whether mid-term local results signal terminal decline or a recoverable slump.

SNP wins first Holyrood majority (2011)

May 2011

What Happened

The Scottish National Party won 69 of 129 Holyrood seats — an outright majority that the parliament's proportional system was designed to make almost impossible. Alex Salmond used the result to claim a mandate for an independence referendum, which the UK government accepted.

Outcome

Short Term

The Edinburgh Agreement of October 2012 transferred the legal power to hold a referendum to Holyrood under a section 30 order.

Long Term

Scotland voted 55%-45% against independence in September 2014; the question has remained live in Scottish politics ever since.

Why It's Relevant Today

John Swinney's stated benchmark for success — an SNP majority — is explicitly modelled on the 2011 result and the constitutional leverage it produced.

Welsh Assembly first elected (1999)

May 1999

What Happened

Following a narrowly approved 1997 referendum, Wales held its first elections to a 60-member National Assembly with limited devolved powers. Labour won 28 seats, Plaid Cymru 17, and a Labour-led administration was formed under Alun Michael.

Outcome

Short Term

The Assembly began operating with secondary-legislation powers only, drawing criticism from both nationalists and unionists for its limited remit.

Long Term

Powers were progressively expanded through the 2006 Government of Wales Act, the 2011 referendum on primary law-making, the 2017 Wales Act, and the 2024 Senedd reform act.

Why It's Relevant Today

The 96-seat Senedd debuting today is the culmination of a 27-year expansion of Welsh devolution, and the first election in which Plaid Cymru is favoured to lead the government.
