South London (South London News) April 3, 2026 – Staff at Marks & Spencer are voicing growing fears about their safety at work amid a sharp rise in shoplifting and retail crime, with the high street giant calling on the Government to take decisive action.

A senior executive revealed that customer-facing employees endure daily violence and abuse, including a shocking incident last week where one worker was hospitalised after ammonia was thrown in their face. This comes after chaotic scenes at an M&S store in Clapham, south London, where hundreds of youths overwhelmed high street shops in what appears to be a coordinated online trend.

The retailer’s outspoken response highlights a broader crisis gripping UK high streets, with M&S leaders directly challenging both national and local authorities. In a candid message posted on the company’s website, M&S retail director Thinus Keeve lambasted the lack of support, writing:

“Without a government seriously cracking down on crime and a Mayor that prioritises effective policing we are powerless.”

Mr Keeve has personally written to Mayor of London Sadiq Khan, while M&S chief executive Stuart Machin has penned a letter to Home Secretary Shabana Mahmood, demanding urgent intervention.

What Triggered M&S’s Public Outcry?

The immediate catalyst was unrest earlier this week at the M&S store in Clapham, south London. Reports describe hundreds of youths swarming high street shops, including the M&S outlet, as part of a viral online trend encouraging mass gatherings and disorder.

This incident has amplified long-standing concerns about retail crime, pushing M&S bosses to speak out forcefully.

As reported across multiple outlets, the Clapham event underscores a pattern of escalating threats to retail workers. The retailer claims its staff are subjected to violence and abuse every single day, with the ammonia attack serving as a grim example.

One staff member required hospital treatment following the assault, highlighting the physical dangers now routine in stores.

Who Are the Key Figures Speaking Out at M&S?

M&S retail director Thinus Keeve has been at the forefront, using the company’s website to criticise political leaders directly. In his message, Mr Keeve stated:

“Without a government seriously cracking down on crime and a Mayor that prioritises effective policing we are powerless.”

He has followed this up by writing to Sir Sadiq Khan, the Mayor of London.

Meanwhile, M&S chief executive Stuart Machin has escalated the matter nationally by writing to Home Secretary Shabana Mahmood, calling for more to be done to protect retail workers. These letters represent a coordinated push from the top of the organisation.

Adam Hawksbee, head of external affairs at M&S, provided further insight during an appearance on BBC Radio 4’s Today programme on Friday. As reported by BBC News journalists, Mr Hawksbee said: “Retail crime has always been a challenge, but it does feel in the past weeks and months that the problem is getting worse.” Addressing the human toll, he added:

“Our colleagues are really resilient and they will always manage these incidents in the best way they can, but it clearly has an impact.”

Why Are M&S Staff ‘Worried’ About Coming to Work?

The fear among M&S employees stems directly from daily encounters with violence and abuse. The company has publicly stated that customer-facing staff are targeted routinely, with the recent ammonia incident exemplifying the severity. One worker was taken to hospital after the chemical attack last week, a detail confirmed in statements from M&S leadership.

Mr Hawksbee elaborated on BBC Radio 4’s Today programme, noting the emotional strain despite staff resilience.

“Our colleagues are really resilient and they will always manage these incidents in the best way they can, but it clearly has an impact,”

he said, as covered by BBC journalists. This admission paints a picture of a workforce under siege, worried about personal safety just to perform their jobs.

Broader context from M&S indicates that shoplifting has intensified, with the Clapham unrest acting as a flashpoint. The online trend fuelling the youth swarms has added an unpredictable element, turning shops into targets for chaos.

What Happened in the Clapham Unrest Involving M&S?

Earlier this week, an M&S store in Clapham, south London, was caught in the midst of significant disorder. Hundreds of youths swarmed high street shops, overwhelming security and causing widespread alarm. This was linked to an online trend promoting such gatherings, as detailed in initial reports from the retailer and local coverage.

The incident at the Clapham branch has been cited by M&S as emblematic of wider failures in policing and crime prevention. No arrests or specific injury details from this event were mentioned in the company’s statements, but it prompted the swift response from executives.

How Has Retail Crime Evolved Recently?

Adam Hawksbee addressed this on BBC Radio 4’s Today programme, stating: “Retail crime has always been a challenge, but it does feel in the past weeks and months that the problem is getting worse.” This assessment aligns with M&S’s claim of daily violence against staff, including the ammonia assault that sent one employee to hospital.

The retailer positions itself as powerless without stronger intervention, a view echoed in Mr Keeve’s website message and the letters to Sir Sadiq Khan and Shabana Mahmood. The combination of opportunistic shoplifting, abuse, and organised unrest like Clapham signals a deteriorating environment for high street operations.

What Actions Has M&S Taken Against the Government and Mayor?

M&S has pursued direct advocacy. Thinus Keeve wrote to Sir Sadiq Khan following his website post criticising the Mayor’s policing priorities. Separately, Stuart Machin contacted Home Secretary Shabana Mahmood, urging comprehensive measures.

These steps follow the Clapham incident and the ammonia attack, framing M&S’s stance as a response to immediate threats. Mr Keeve’s message explicitly ties government inaction to the retailer’s vulnerability:

“Without a government seriously cracking down on crime and a Mayor that prioritises effective policing we are powerless.”

What Is the Broader Impact on M&S Staff?

Staff worries are palpable, with executives like Adam Hawksbee highlighting resilience amid strain. “It clearly has an impact,” Mr Hawksbee told BBC Radio 4’s Today programme, as reported by BBC News. Daily violence, abuse, and extreme cases like the hospitalisation after ammonia exposure have eroded confidence.

M&S portrays its workforce as dedicated yet endangered, managing incidents professionally but at personal cost. The Clapham swarming incident has intensified these fears, linking individual assaults to larger mob actions driven by online trends.

Will the Government and Mayor Respond to M&S’s Calls?

No official responses from Sir Sadiq Khan or Home Secretary Shabana Mahmood have been reported as of April 3, 2026. M&S’s letters represent a formal escalation, building on public statements from Thinus Keeve and Adam Hawksbee.

The retailer’s message underscores a perceived policy gap, with Mr Keeve demanding a “government seriously cracking down on crime” and a Mayor focused on “effective policing.” Coverage from BBC and other sources notes this as part of a growing chorus from retailers facing similar woes.

How Does This Fit into UK Retail Crime Trends?

M&S’s warnings align with reports of surging shoplifting nationwide. The ammonia incident and Clapham unrest illustrate a mix of individual aggression and group disruption. Adam Hawksbee’s observation of worsening conditions in recent weeks and months suggests an acceleration.

Staff fears, as voiced through leadership, reflect a sector-wide issue. M&S’s proactive letters to key figures position it as a leader in pushing for change, though outcomes remain uncertain.
