Nigeria has criticised the UK’s travel restrictions after it was placed on the red list amid fears over the Omicron Covid-19 variant.
“What is expected is a global approach, not selective,” Sarafa Tunji Isola, Nigeria’s high commissioner to the UK, told the BBC on Monday.
He also echoed comments made by the UN’s chief, who described restrictions imposed on some southern African countries as “travel apartheid”.
New rules came into force at 04:00 GMT.
It means travellers arriving from Nigeria will be required to enter hotel quarantine – at their own expense – and isolate for 10 days.
