British tourists flying home on Sunday after a holiday in Spain angrily reacted to an abrupt decision by their government to make everyone arriving from the Mediterranean country spend 14 days in quarantine.

Britain's decision late on Saturday to take Spain off a safe-travel list over a rise in coronavirus cases took effect from midnight, leaving travelers with no time to dodge it, and with major concerns about their returns, tourists at Madrid's Barajas airport said.

"It's really bad because it's just come all of a sudden, it's not given very much time to prepare so everyone is now panicking," said Emily Harrison, from Essex, who was taking a flight to London and faced the prospect of having to self-isolate for two weeks.
