State forces and Security Forces confirmed that there were no serious incidents in the Balearic Islands, where most people followed the rules, although some did have to be reminded about social distancing.

Mr Cosa took to Twitter to say Spain is a great country...of fools.
The reckless behaviour of those who blatently broke the rules has been met with angry complaints and harsh criticism on social media.
