May Brown, a Nigerian woman with leukemia, made the news last week when her sister was denied entry to the UK to provide life-saving stem cells. The Home Office said it wasn’t satisfied that the trip was genuine, or that the sister had enough money. This isn’t the first time Brown has been on the wrong side of British immigration; denied asylum in 2013, she attempted suicide. ‘We are sensitive to cases with compassionate circumstances,’ a Home Office spokesperson said last Friday, ‘but all visa applications must be assessed against the immigration rules.’
