Mahmood’s migration changes will deliver fraction of claimed savings, data suggests

Exclusive: Analysis of government figures indicates public finances will gain 600m not 10bn if migrants' access to benefits is reduced

Shabana Mahmood's migration changes are expected to save just 600m - about 6% of the 10bn the home secretary claimed, according to the government's own data.

Under the plans, most people would have to wait 10 years to qualify for settled status, rather than the existing five-year period, which the home secretary argued would save costs on public services.
