Spain could impose a 14-day quarantine on visitors from the UK unless the British Government lifts its own isolation rule.
Officials in Madrid said Britons would be allowed to enter Spain from June 21, which is 10 days earlier than originally stated, but foreign affairs minister, Arancha González Laya, has now said that the quarantine could be now be introduced.
She warned in an interview on the BBC that restrictions may be imposed just for British visitors because of the coronavirus pandemic, MirrorOnline reports.
She said: "We will be checking what the UK will be doing and we will be in a dialogue with the UK to see whether or not we should be introducing reciprocity as they have different measures than the rest of the European Union."
She claimed the situation was "fluid" and said officials would "properly engage in a dialogue with the UK authorities to make sure that we both take the message that best corresponds to the health situation, which today is a little bit better in Spain than it is in the UK".
"Hopefully by the time we open our borders, the UK would have moved forward also," she added.
The number of cases and fatalities in Spain continues to decline, with just 27 deaths in the last week. A total of 27,136 deaths have been recorded across the entire country.
Currently, the Foreign Office warns against all but non-essential travel abroad.
Travellers returning to the UK face 14 days of isolation under mandatory quarantine rules - with fines threatened for anyone who flouts the rules.
But sources have claimed that travel to low-risk countries could soon be allowed, in order to restart the economy.
Travel bosses firmly opposed to the guidelines claim that government sources have privately confirmed that 'air bridges' will be in place by the end of the month.
These would allow travellers arriving from countries where the risk of being infected by the virus is deemed low enough being able to dodge quarantine.
