Sure, they're ruining it by:
Refusing to engage in internal accountability or review processes e.g., Robert Ford who point blank refused to engage in internal investigations after a series of complaints from women were made against him.
Obstructing oversight and governance functions e.g., attempting to bypass establish procedures to access sensitive/confidential data and threatening staff with gross misconduct if they resist.
Undermining transparency and restricting media access e.g., banning local press from interviews or restricting journalists’ access to councillors and council information (granted that wasn't Kent but still Reform).
Appointing inexperienced individuals to senior or sensitive roles e.g., placing very young or inexperienced councillors in key cabinet positions overseeing complex portfolios and massive budgets.
Internal infighting and bullying behaviour
e.g., the example in the OP
Ignoring or failing to act on statutory duties
e.g., cancelling crucial committee, community and/or scrutiny meetings, delaying audits beyond statutory deadlines.
Making misleading claims about financial performance or savings e.g., publicising supposed millions in savings that were later disputed or unverified by finance officers.
Creating instability through frequent leadership changes e.g., multiple leadership resignations and reshuffles within months, causing confusion and disruption to governance continuity and costing the tax payer hundreds of thousands.
Intimidating or threatening council officers
e.g., implying that failure to comply with political instructions or information requests could result in disciplinary action.
Withholding or manipulating information from opposition members e.g., refusing to allow opposition councillors to review their doge report before publishing it and refusing to provide sources for the data within the report after accusations of it being misleading, superficial and derived from X not internal data.
But I'm sure you'll ignore all this and find a way
to defend them still 😅
