A flight bringing British evacuees from the coronavirus-hit Diamond Princess cruise ship is due to arrive on Saturday morning after leaving from Japan.
Thirty-two British nationals are on board the plane, which was delayed until Saturday. A small number of nationals from European nations will also be on the flight, alongside British government medics, it is understood.
The number of Britons on the aircraft is lower than the 78 initially expected; some are in hospital while others will remain on the vessel.
The aircraft is due to land at Boscombe Down Ministry of Defence base, near Salisbury in Wiltshire, with passengers to then be taken to Arrowe Park Hospital on the Wirral for 14 days of quarantine.
