Southwark Council Faces Political Turmoil as Fourth Labour Councillor Joins Greens
Southwark Council has been plunged into a deepening political crisis as former council leader-elect James McAsh became the fourth Labour councillor in just four months to defect to the Green Party. The Liberal Democrat opposition has declared the council is now in "political freefall" ahead of crucial local elections scheduled for May 7, 2026.
McAsh's Defection and Criticism of Labour
Councillor James McAsh, who has represented Goose Green ward since 2018 and served as Cabinet Member for Clean Air, Streets and Waste until his defection, announced his move to the Green Party on Wednesday, February 18. In a scathing critique of his former party, McAsh stated that Southwark Labour "cannot and does not stand up to the government" and that he could no longer "in good conscience tell residents to vote Labour."
The former Labour leadership hopeful explained: "I grew up in a Labour household and I've devoted much of my adult life to the party. I'm proud of the work I've done in Southwark - but Labour is no longer the vehicle for social justice I once thought it was."
McAsh, who is a primary school teacher and trade unionist, emphasized that his political life has been defined by fighting austerity, beginning with campaigns against Liberal Democrat tuition fees and university cuts. He praised Green Party leader Zack Polanski for "already speaking the truth and standing up for Southwark residents."
Leadership Controversy and Previous Defections
The defection follows a controversial leadership contest within Southwark Labour last summer. McAsh was initially elected as leader of the Southwark Labour group and effectively the council, but his victory was overturned by the national Labour Party after concerns were raised by MP Neil Coyle about proxy voting procedures.
A subsequent online election saw Sarah King elected as the new leader, though three councillors - Sam Foster, Ketzia Harper, and Laura Johnson - questioned the "legitimacy" of her election and threatened to quit Labour, accusing their own party of interfering with democratic processes.
Since King became leader in July, Southwark Labour has lost seven councillors who have either defected to the Greens or now sit as independents. McAsh joins former Labour councillors Sam Foster, Reginald Popoola, and Kath Whittam, who have all defected to the Greens since November 2025.
Political Reactions and Election Implications
Councillor Victor Chamberlain, Leader of the Liberal Democrat Opposition on Southwark Council, declared: "Labour's own psychodramas are once again proving to be its downfall, with controversial Labour MP Neil Coyle's interference now coming back to bite his party. They are in political freefall, and the writing is on the wall for them in the local elections in Southwark and across the country."
Chamberlain added that while "Labour collapse into self-indulgent political chaos and scandal, Liberal Democrats are laser focused on serving our residents, and campaigning on the housing crisis, rising crime, and the cost of living."
A senior Southwark Labour spokesperson responded to McAsh's departure by stating: "Local residents can draw their own conclusions about Cllr McAsh's swift move from Labour leadership hopeful to the Green Party, after he didn't get his own way. While he's thinking about his own career Southwark Labour are delivering for residents."
Green Party Welcomes New Member
Zack Polanski, Leader of the Green Party, expressed pride in welcoming McAsh to the party, describing him as "a hard-working and principled champion for his community."
Polanski criticized Labour, saying: "Labour is more interested in toxic factionalism than choosing the best people to represent local communities, such as James, a primary school teacher and trade unionist. I cannot wait to work with James, and many others like him, for an agenda of real hope and real change. Where Labour sides with billionaires and property developers, we will side with working people and communities."
The political landscape in Southwark continues to shift dramatically as the council approaches May elections, with all parties positioning themselves for what promises to be a highly contested battle for control of the local authority.
