Kate Middleton’s brother James embroiled in nasty feud

As she battles cancer and her parents deal with serious money woes, Kate Middleton’s brother is now embroiled in a nasty feud.

Kate Middleton’s brother, James Middleton, is reportedly feuding with a “nightmare neighbour” who is allegedly trying to attack his family.

The mental health advocate, 37, claims in a new report from The Independent that David Alderton, 65, has put up malicious posters around their Stanford Dingley village and frequently complains about noise and light pollution coming from the family farm in Berkshire.

This new family drama comes as Kate battles cancer – and her mother Carole is reportedly doing everything she can to shield her daughter from the family’s money woes, including a massive $450,000 debt.

Per the outlet, Alderton runs a motorcycle dealership and lives in a bungalow opposite Middleton’s farm. He allegedly fell out with the adjacent royal after joining a group that objected to a planning application tendered by James – and has now warned Kate’s sibling that “things are gonna get brutal.”

Their relationship has allegedly become so nasty that James has reportedly asked that they communicate only via email or the local council, noting that a mediation program did nothing to quell the vitriol.

“Mr Alderton has a history of disputes with neighbours within the village,” James told the outlet. “In 2017 he took legal action against the parish council and a parishioner, and intimidated locals for objecting to a series of planning applications, all of which were refused.”

Page Six has reached out to both parties for comment but did not immediately hear back.

Alderton declined to give a statement to The Independent regarding the most recent report. However, he alleged to the Daily Mail in February 2023 that James uses “clearly unsuitable machinery” that releases “unwelcome toxic and noxious” fumes.

“It’s ancient, noisy, dirty, smelly machinery, old Massey Fergusons, an old threshing machine, wood chipping machines, you name it,” he claimed at the time. “It’s a farm so I suppose he thinks he feels justified in having farm machinery even if it’s derelict. But he has a duty of care to his neighbours and the environment – it should not impact on people nearby.”

The father of one disputed the allegations at the time.

“It is sad that someone who chooses to live in the countryside in a farming community cannot accept that from time to time there will be noise and smells from tractors and animals, especially if they live next to a farm,” James explained.

“We would be neglecting our duty of responsibility for the animals and countryside if we did what he asked us to do to our livestock.”

Per The Independent, everything took a bizarre turn last July when James and his family went on holiday and had a housesitter stay to look over their property.

The family dogs allegedly scared some guinea fowl, which caused the birds to squawk and prompted Alderton to march over and yell at the housesitter.

“Shut those f – king birds up, you noisy c**t,” he reportedly said.

James told The Independent that he first approached authorities following the birth of his son, Inigo, whom he welcomed with wife Alizee Thevenet in October 2023.

“Police were contacted shortly after our son was born as we became increasingly concerned by the activities surrounding a neighbour,” he shared, noting that the dispute has caused many problems.

“[Mr Alderton’s actions] bred animosity in the community, rumor, ill feeling, and caused myself and my family anxiety and distress.”
