UK says always reviewing quarantine data, no comment on Portugal shift

LONDON, Sept 1 (Reuters) - Britain continues to keep its
quarantine policy under review, Prime Minister Boris Johnson's
spokesman said, but declined to comment on media reports that
Portugal will be added back onto the government's quarantine
list due to rising case numbers.

"We keep the data for all countries and territories under
constant review. I'm not going to pre-empt any potential
changes," he said when asked about the reports.
