All British nationals have been urged to leave China due to the coronavirus outbreak, as the epidemic claimed more than 420 lives and infected more than 20,000 people globally.

Meanwhile, British officials are continuing attempts to trace 239 people who flew to the UK from Wuhan, the city at the centre of the outbreak, before travel restrictions came into force.

Some 94 UK nationals have been evacuated from the city to Britain and are now undergoing 14 days in quarantine at Arrowe Park Hospital on the Wirral.
