Prominent legal commentator Joshua Rozenberg KC has raised serious concerns about what he describes as an 'unusual' decision by Cheshire Police's chief constable to write a formal letter accusing former Cabinet minister Sir David Davis of misleading parliament. The controversy centres on comments made by Sir David regarding the police investigation into convicted killer nurse Lucy Letby.
Parliamentary Debate Sparks Police Backlash
During a parliamentary adjournment debate on March 26, Sir David Davis made explosive allegations about Cheshire Police's handling of Operation Hummingbird, the years-long investigation into baby deaths at the Countess of Chester Hospital. The veteran MP claimed the force had committed 'egregious failures' during their inquiry into Letby, who was convicted of murdering seven infants and attempting to murder six others.
Chief Constable's Strongly Worded Response
In a remarkable development, Chief Constable Mark Roberts responded with a strongly worded letter dated April 8, which has been obtained by the Daily Mail. The correspondence, sent to Cheshire MPs, the Police and Crime Commissioner, and Commons Speaker Sir Lindsay Hoyle, accused Sir David of making 'materially inaccurate and misleading' statements about the investigation.
The police chief alleged that the MP had failed to check 'basic facts' about Operation Hummingbird and demanded that Sir David correct the parliamentary record 'without delay'. This direct intervention by a senior police officer into political debate has raised significant questions about appropriate boundaries between law enforcement and parliamentary scrutiny.
Rozenberg's Critical Analysis
Speaking to the Daily Mail's Trial podcast, Joshua Rozenberg KC expressed his concerns about the police chief's approach. 'This is a very striking letter,' Rozenberg noted. 'What it demonstrates is that the Chief Constable is pretty cross at what he's heard in this debate. Fed up with the criticism of his force.'
The legal expert continued: 'Roberts thinks he's done everything by the book. That they got the right result, that the legal process has operated properly. But, an awful lot of people don't.' Rozenberg acknowledged the emotional complexity of the case, stating: 'The idea that a neonatal nurse would murder babies is such an appalling prospect, it's not surprising people don't want to believe it.'
Questioning Police Conduct in Public Debate
Rozenberg offered a pointed critique of the police chief's decision to enter the public fray in this manner. 'It's not Roberts' job to be cross though, it's not his job to be offended. It's not his job to be annoyed by public criticism,' he argued. 'His job is to investigate crimes, to present evidence and ultimately, to allow the courts to decide where truth lies and justice rests.'
The legal commentator described the police chief's actions as 'not very seemly' for a senior police officer, particularly noting the selective distribution of the letter to certain MPs with the apparent expectation it would enter public discourse. Rozenberg characterised this as a 'curious' move for a police force, suggesting it represented an unusual approach to managing public criticism.
Sir David Davis's Persistent Concerns
Sir David Davis has emerged as one of the most outspoken critics of Lucy Letby's convictions, maintaining his belief that she may be the victim of a massive miscarriage of justice. During the March parliamentary debate, he presented several specific criticisms of Cheshire Police's investigation methodology.
The MP alleged that officers had developed 'tunnel vision' by focusing exclusively on Letby as their prime suspect, relied too heavily on a single medical expert's opinion, and failed to adequately pursue alternative explanations for the infants' deaths. These claims have placed the police investigation under intense scrutiny and prompted broader questions about investigative procedures in complex medical cases.
Police Rebuttal of Allegations
In his detailed response, Chief Constable Roberts systematically addressed Sir David's criticisms, arguing that many allegations 'do not hold up to scrutiny'. The police chief emphasised that multiple medical experts across different specialities had been involved in Operation Hummingbird, contradicting claims of over-reliance on a single expert.
Furthermore, Roberts revealed that Cheshire Police had spent thirteen months meticulously examining the babies' deaths before Lucy Letby was even designated as a suspect. This timeline challenges suggestions that investigators rushed to judgment or failed to conduct thorough preliminary inquiries.
Broader Implications for Police-Parliament Relations
The escalating dispute raises important questions about the appropriate relationship between police forces and elected representatives. Rozenberg acknowledged that both parties had legitimate roles to play, stating: 'Davis is right to make his concerns known. The Chief Constable is right to reply.'
However, the legal expert suggested a more constructive approach would involve direct communication rather than public confrontation. 'But it would be better if they spoke to one another rather than doing it through the media,' Rozenberg advised, highlighting concerns about the politicisation of police investigations and the potential chilling effect on parliamentary scrutiny of law enforcement agencies.
The controversy continues to develop as both sides maintain their positions, with the broader legal community watching closely how this unusual clash between parliamentary privilege and police authority will be resolved. The case has already prompted discussions about accountability mechanisms and the boundaries of appropriate criticism for police investigations into high-profile criminal cases.
