A British nurse who was diagnosed with Ebola after returning from Sierra Leone remains in a critical condition in hospital.

The Royal Free Hospital in London said yesterday it was sorry to announce that the condition of Pauline Cafferkey has gradually deteriorated over the past two days.

Ms Cafferkey, from South Lanarkshire, was given an experimental anti-viral drug and blood from a disease survivor.

Meanwhile, a patient who was tested in Swindon for Ebola has tested negative.
