A leading Swedish opposition party has promised an urgent reprieve for British nationals facing deportation from the country over Brexit administrative issues.

Niels Paarup-Petersen, the migration spokesperson for the Centre party, said it would introduce laws to end the suffering of people such as the 78-year-old British widow Joyce Thomas if, as polls project, it forms a new centre-left coalition after the general election in 10 days’ time. Thomas has been told to leave by next Wednesday after 21 years in Sweden.
