(Reuters) – Daniel Northover left his home in Liverpool this month, which marks the 10th anniversary of Britain’s Brexit ​referendum, to move in with his 80-year-old mother in Turre, a town of 4,500 people in Andalusia in southern Spain.

After his stepfather died in summer, Northover, 53, has taken turns with his sister to travel back and forth to Spain to care for his mother Carole, who cannot cook, clean or dress by herself after suffering several strokes.

But with non-EU residents only allowed to remain in the bloc for 90 days in every 180 without a visa, he said it had become unsustainable. A project manager for local councils ​and charities, Northover did not meet the requirements for a working visa. Visas to care for a dependent family member are only available if it is ​the UK citizen needing the care.
