Travellers have been warned by Manchester Airport officials they could face "longer immigration queues" today.
On Wednesday, March 15, some Border Force staff are taking part in strike action, meaning disruption may be caused. Staff with the Public and Commercial Service (PCS) union started the industrial action this morning and it will continue until around 7am on Thursday, March 16.
The industrial action is taking place at all UK airports and maritime ports. This could lead to delays at border control for those arriving in the country, the MEN reports.
