Error caused by flaws in system of eVisas meant people entitled to benefits were told support would be stopping

A minister has apologised after people entitled to benefits wrongly received letters informing them their financial support was being axed, the Guardian has learned.

The error was due to flaws in the system of eVisas, concerns about which have been raised over whether they will work when people travel overseas and then try to return to the UK. The new visas come into force at the end of this month, although the government has extended the grace period for those using the eVisas to return to the UK when they’re abroad until next March.
