British Ambassador to Spain Hugh Elliott has released a video message informing citizens of the "big implications" of the drastic measures brought in on Saturday by the Spanish government due to the coronavirus crisis.
The message comes after the British government advised against all but essential travel to Spain and recommended that all tourists return home.
The ambassador reminds residents and tourists still in Spain that the key requirement of the government's decree is to stay at home and only go out for very specific reasons.
These include to buy food and other essential items and medication, to go to a hospital or health centre, to go to work - if working at home is not possible - and to carry out caring duties.
"It's really important that we all comply with this," said the ambassador, reminding British nationals that the aim of the measures is to curb the spread of the coronavirus.
The embassy has also advised British nationals to sign up for alerts to receive the latest travel advice regarding Spain from the British government.
The Spanish government has not restricted flights to the UK, said the ambassador and tourists are expected to be able to return home, although they are encouraged to check with their airline or travel company.
"Wherever you are in Spain you should follow the instructions of the local authorities," stressed the embassy in a statement.
"These are challenging times," said the ambassador, who finished his message by saying "a big thank you" to the Spanish health professionals.
