Back in March, the FCO advised UK nationals against all non-essential travel worldwide for an initial 30 days.

However, this was extended to an "indefinite period" in early April, a move the travel sector has been staunchly critical of; many travel professionals believe it is confusing for clients looking to book further out, and stifles longer-term demand as the sector looks to recover.

However, at the weekend, the FCO dropped "indefinite period" from its advisory.

The new wording reads: "The Foreign and Commonwealth Office currently advises British nationals against all but essential international travel. This advice is being kept under constant review."

The alteration came ahead of the UK being formally placed under quarantine from 12.01am on Monday (8 June). All arrivals, by air, sea or rail, will be required to self-isolate for two weeks.

The policy will be reviewed on a three-weekly basis. Home secretary Priti Patel has confirmed the FCO is exploring so-called air bridges or safe travel corridors with countries with lower rates of coronavirus infection to allow anyone travelling, or returning, to the UK to avoid the two-week self-isolation requirement.

Any air bridge arrangements would however, require the FCO to at least partially lift or amend its advisory. The quarantine policy is due its first review at the end of June.
