London Mayor Sadiq Khan has issued a stark warning to the Labour Party following its devastating third-place finish in the Gorton and Denton byelection in Greater Manchester. The result, which saw Labour lose a seat it had held for nearly a century, represents a profound political fracturing that cannot be ignored.
A Flawed Strategy of Taking Progressive Voters for Granted
Khan argues that Labour's current approach of attempting to channel Reform UK while taking liberal, progressive voters for granted represents a fundamentally flawed strategy. Many who voted Labour in the July 2024 general election are now angry and frustrated, impatient to see the promised changes including better public services and economic growth.
The threat to Labour in some parts of the country is now existential, according to Khan, who draws parallels with how the party lost its Scottish strongholds in the 2000s. Without a change in course, Labour risks repeating this pattern in other regions.
Learning from London's Progressive Success
Khan points to his own electoral successes in London as evidence that bold, progressive policies can win elections. Contrary to perceptions, London has the same mix of voters as the rest of the UK, yet Labour has consistently won there by putting progressive policies at the center of its agenda.
Key achievements Khan highlights include:
- The Ultra Low Emission Zone (Ulez), which has proven both effective and popular in tackling air pollution
- Free school meals for all state primary schoolchildren in London
- Record levels of council house building, reaching the highest rate since the 1970s
- Crime prevention initiatives that have reduced homicides to their lowest level since records began
The Danger of Competing with Reform on the Right
Khan warns that staying quiet on critical issues and trying to compete with Reform UK on the right of politics feels inauthentic and represents a betrayal of Labour's core values. He emphasizes that the vast majority of potential Green voters are not extreme but share Labour's values while being disappointed with the government's performance.
"Calling them extreme will only turn more people away," Khan states, noting that in his mayoral elections, he successfully asked Green supporters to lend him their votes based on shared progressive values.
Standing Up for Core Values
The London Mayor outlines several areas where he believes Labour must be more vocal:
- Honestly addressing the damage caused by Brexit and advocating for rejoining the single market and customs union
- Speaking out against the horrific situation in Gaza where innocent Palestinians continue to be killed
- Celebrating diversity as a strength rather than a weakness
- Calling out racism, sexism, and Islamophobia wherever it appears
Khan warns that failing to unite progressives risks opening the door to Reform UK, a party he describes as taking inspiration from Donald Trump and promising policies that would send shivers down the spine of every minority community in Britain.
A Call for Bravery in Convictions
While Khan does not advocate for a change in leadership, he insists there must be real change in Labour's approach. The party needs a vision that provides hope for the future rather than doom and gloom, and must be braver in demonstrating its commitment to the core beliefs it was established to promote: equality, fairness, social justice, and internationalism.
"Labour, 126 years after its creation, is still the only party capable of delivering social democratic change in this country," Khan asserts. "But it is time for us to be braver in our convictions and show this to be true – not just in what we do, but in what we stand for."
The Gorton and Denton byelection result serves as a wake-up call that Labour cannot afford to ignore if it hopes to maintain its relevance and electoral viability across the United Kingdom.
