A 74-year-old British man with advanced dementia has been given until 20 August to leave Sweden, despite living there for 25 years and requiring round-the-clock residential care. He lives in full-time residential dementia care in Sweden. On 23 July, the court ruled that the decision requiring Mason to leave Sweden could stand. After 25 years in Sweden, an elderly British man with advanced dementia and a need for round-the-clock care is being told he must leave. The case has become a striking test of what post-Brexit immigration rules mean when they collide with a person's health, family life and decades-long ties to the country they call home.
