Search teams looking for missing British teenager Jay Slater in Tenerife have found a body, police say.
The Guardia Civil said its officers and a mountain rescue unit found the body of a young man in the Masca area.
Mr Slater, 19, was last seen on 17 June, after visiting an Airbnb rented by two people he had been with at a music festival on the island.
A police statement said that "initial evidence" suggested the person found had "suffered an accident or fall in the inaccessible zone".
While not naming Oswaldtwistle apprentice bricklayer Mr Slater directly, the statement said that "all the evidence" suggests the remains found were those of "the young British man who disappeared 29 days ago."
Full identification of the body is yet to be carried out, it added.
The Guardia Civil has not said when the body was found, or exactly where it was discovered.
But the charity LBT Global, which works with families of people missing oversees, said that the remains were found along with Mr Slater's clothes and possessions, close to his mobile phone's last known location.
The group said it was supporting Mr Slater's family.
Mr Slater's father Warren Slater described his disappearance as "a living hell", while his mother Debbie Duncan told of her "pain and agony" as no trace could be found.
Lancashire Police, which had previously had its offer to help with the search turned down by the Tenerife police, said in a statement that it "had today been notified by the Guardia Civil that they have found the body of a man and that the indications are that this is Jay Slater".
The statement added: "While at this stage no formal identification has been carried out our thoughts are very much with Jay’s family at this time, and we continue to offer them our support."
The search for Mr Slater since his disappearance has involved his family, friends, police and specialist mountain rescue teams as well as volunteers from several countries.
But on 30 June, the Guardia Civil said it was calling off its search.
His family continued to look for him, most recently with the help of a group of Dutch mountain rescuers.
The Guardia Civil indicated in its statement that it was members of its Mountain Rescue and Intervention Group who located the "lifeless body" of a young man.
Throughout the month since Mr Slater went missing, his family have refused to give up hope.
On Saturday, a statement of an official fundraising page, which has raised more than £50,000 towards search efforts, described him as a "normal, hardworking young lad from Lancashire who is very loved by all who know him".
"Although we don't have any answers to his disappearance we obviously have to remain positive," his friend Lucy Mae Law posted on behalf of his family.
Search teams have had to contend with difficult terrain throughout their search for Mr Slater.
Tenerife is a volcanic island in the Atlantic ocean archipelago of the Canary Islands, and the area in which Mr Slater was last seen is full of steep cliffs and gorges.
The land is arid and dotted with cacti.
In his last phone call to his friend Ms Law shortly before his phone battery died, Mr Slater is said to have told her that he was bleeding and needed water.
Another friend of Mr Slater, Brad Hargreaves, later said in a television interview that Mr Slater had video called him just before the call to Ms Law, and had indicated he had slipped off the road he was walking.
