Brits on Spain holidays are being warned not to attend "illegal parties" in the likes of Majorca or Ibiza, or face some hefty fines of up to £85,000.
In fact the Foreign Office has subsequently updated its travel advice for Spain, after "a number of serious accidents" have occurred at the unauthorised gatherings, often taking place in private homes or villas in the holiday hotspots such as Majorca and Ibiza.
As reported by the Birmingham Mail, the British Embassy in Spain has warned that not only are these parties not allowed, but they are common across the islands and heavy fines of up to £85,000 are being handed out to those who attend.

In its updated advice, the Foreign Office warns: "There have been a number of serious accidents involving people attending irregular commercially promoted parties in villas and private homes on the islands of Ibiza and Mallorca. Licensed clubs and bars are required to meet safety and security standards, including emergency exits and capacity limits, and to have trained, licensed security staff.
"Irregular commercial parties may not meet these standards. You should take care of your belongings, ensure you know where emergency exits are located and not take unnecessary risks.
"Heavy fines may be imposed by local authorities to anyone attending irregular commercial parties."
Revellers will also need to take note of new rules in Majorca and Ibiza as the Balearics government looks to crackdown on drunken behaviour from tourists.
In fact, a new rule has been introduced which limits the number of drinks Brits can enjoy each day during all-inclusive holidays.
UK holidaymakers will be restricted to six drinks a day, alongside their lunch and dinner, meaning that you'll only be able to have three drinks per meal. Essentially, the new rules will mean Brits won't be able to enjoy drinks by the pool.
The restrictions had been on the cards for a while. Earlier this year, Balearic Islands Tourism minister Iago Negueruela said of the move: "We want British tourists - we don't want this type of tourism.
"British tourism is essential for our islands. We share with the British government the view that some images of British tourists are embarrassing.
"We want to put a stop to bad behaviour. We will increase the police presence in these areas and the number of inspectors - we will have zero tolerance for tourism excesses."
