The British government plans to introduce a quarantine obligation on people coming from Spain, including British tourists there, soon.
According to an employee of The Sunday Times, this should take effect this weekend.
The holidaymakers should then stay at home for two weeks after their return.
London has already listed many countries from which travellers must be quarantined for two weeks after arrival.
Spain would now also be included in that list for fear of the growth in the number of corona infections.
