UK PM warns of second wave in virus spat with Spain

British Prime Minister Boris Johnson warned Tuesday of a "second wave" of coronavirus in Europe as he defended a controversial decision to quarantine all travelers arriving from Spain, despite criticism from Madrid.

Johnson insisted the UK had taken "swift and decisive" action at the weekend to impose a 14-day quarantine on everyone entering Britain from Spain – a major tourist destination for Britons. 

Johnson also said UK would take action to impose quarantines on other countries should COVID-19 infections rise and such measures become necessary.

"I'm afraid if we do see signs of a second wave in other countries, it is really our job, our duty, to act swiftly and decisively to stop travelers coming back from those places seeding the disease here in the UK," he told reporters.
