Ghana’s High Commissioner in London has appealed to Britain to bring Ama Sumani back from Ghana.
Ama Sumani was taken from a Cardiff hospital on Wednesday where she has been receiving dialysis after cancer damaged her kidneys.
Ms Sumani, 39, whose visa has expired, says she cannot afford care in Ghana.
High Commissioner Annan Cato urged the government on Radio Four’s The World Tonight to allow her back to the UK.
He said the decision to deport her was regrettable and he appealed to the UK, which he said he considered to be a “very compassionate country”.
Mr Cato said: “Even now don’t think it is too late for them to reconsider position to allow her to come back and receive treatment. I would appeal to them to do so.
