The Liberal Democrats have called on the home secretary to “move at speed” to delay the rollout of new border controls that could result in British dual nationals being blocked from entering the country.

A letter sent by the party to Shabana Mahmood echoes one sent by the former Conservative cabinet minister David Davis on Friday asking for a grace period to be implemented urgently after one of his constituents living in the Netherlands told how she could no longer visit her dying mother in a care home in Yorkshire.
