A row over Montenegro’s new embassy in central London has escalated to the High Court, with a neighbour suing Westminster City Council over the impact she says the diplomatic presence has had on her mental health.
Diana Simpson, 35, who lives with her parents on Cambridge Street in Pimlico, is applying for judicial review and potential damages. She has been diagnosed with clinical anxiety and says the council failed to account for it, long Covid and functional neurological disorder when granting planning permission for the embassy’s change of use and its flagpole.
Simpson, the daughter of a former US diplomat who has lived on the street for more than three decades, receives disability benefits. She claims the embassy’s arrival has disrupted her sleep and triggered panic responses. In her statement of grounds, she alleges: “I frequently feel the need to sleep in an alternative to my lifelong bedroom, to gain some marginal relief; sometimes pre-emptively, sometimes in the middle of the night when I cannot reason with my activated primal ‘fear’ brain response.”
From neighbours’ objections to flag complaints
The dispute began quietly this spring when residents raised concerns about the embassy’s appearance. One submitted that the flagpole and Montenegro’s red flag with gold border “stick out like a sore thumb” among the Grade II-listed homes designed by Thomas Cubitt in the late Regency period. Another called the flag “gaudy” and said it was “out of keeping with the quietly dignified” character of the street.
Frustrated by the lack of a planning application before the flagpole was installed, some neighbours were mollified when the embassy’s chargé d’affaires held a gathering with drinks and canapés. One resident remarked dryly: “Perhaps it would have been diplomatic to have done that at the start.”
Simpson, however, has pursued the matter through the courts. She is citing breaches of human rights and equality legislation, arguing the council acted irrationally and delivered a flawed public consultation. She has stated she is questioning whether it “remains tenable” for her to continue living in the house, saying a move would separate her from her “local tight-knit community.”
Council denies allegations
Westminster City Council has denied the allegations in its defence statement, asserting: “There is no plausible interference with the claimant’s home or her private and family life.” The council is seeking summary judgment without a hearing. A spokesperson said: “Councils are legally required to take decisions in line with existing planning policy. It would not be appropriate to comment further at this stage.”
The case, being heard by Justice Mould, reflects a broader tension in London’s affluent neighbourhoods as smaller nations relocate their embassies to less expensive areas.
Embassies spreading across London
Major powers typically cluster in Belgravia, South Kensington, Knightsbridge and Mayfair. Smaller nations have moved their embassies to residential streets in Pimlico and Kensington as they seek to economise on rent.
Turkmenistan recently opened an embassy in another converted family home on Victoria Road in Kensington, prompting similar complaints from neighbours. One local submitted to the Royal Borough of Kensington and Chelsea: “I cannot understand the lack of courtesy afforded to immediate neighbours.” That complainant later acknowledged the Turkmens had turned out to be “actually quite quiet” with no problems “so far.”
By contrast, North Korea’s embassy in Ealing, in a seven-bedroom 1920s home off the A406, has operated with little notice from neighbours. A retired solicitor living nearby said: “We never heard a peep from them.”
