Police being dispatched to Magaluf and Ibiza to help Spanish police with drunk revellers
British police will be dispatched to party destinations Ibiza and Magaluf to help Spanish police deal with victims and offenders from the UK.
A sergeant and a constable will work alongside officers from the Guardia Civil during a two-week trial.
The officers, from West Midlands Police, will spend a week in Magaluf in Majorca followed by seven days in San Antonio, Ibiza.
Both are hugely popular venues for young British and Irish revellers, and Magaluf hit the headlines earlier this summer when holidaymakers defied new rules aiming to crack down on drunkenness.
The trial, funded by the Foreign Office, will see the two officers patrol alongside Spanish colleagues in tourist hotspots including beaches, airport terminals and town centres.
The National Police Chiefs Council (NPCC) said they will assist the Guardia Civil when British nationals are victims of crime, support any criminal investigations where Britons are victims, witnesses or offenders, and help British nationals who are victims of domestic violence, sexual abuse or other serious offences.
The officers will wear full British uniform and work eight-hour shifts between 7am and 10pm, starting on Monday.
Police from France, Germany, Italy, Portugal and Morocco have already taken part in similar initiatives in Spain.
Chief Constable Andy Marsh, NPCC lead on international policing, said: "This trial deployment of officers to work alongside the Guardia Civil is a further step in developing these strong links and builds on the success that Spanish colleagues have seen when working with colleagues from other countries in a similar way.
"Their presence will offer reassurance to both locals and UK citizens in areas that significantly increase in population during the busy summer holiday season and provide support to victims of crime during what can be a traumatic experience, especially when away from home."
West Midlands Police Deputy Chief Constable Dave Thompson said the force is keen to support European police co-operation.
He added: "We are pleased to offer this support, which is fully funded, to Spanish colleagues and is done to help and support the safety of UK nationals."
Simon Manley, British ambassador to Spain, said the trial reflects "close co-operation" between the two countries on policing and security matters.
"The presence of UK police officers will help to remind British holidaymakers of the importance of respecting local laws and customs, ensuring that everyone has a safe and enjoyable holiday, free from trouble and crime," he said.
In June new measures were introduced in Magaluf, including a ban on drinking alcohol on the street between 10pm and 8am, but the resort still witnessed drunken scenes that have made it infamous.
Last summer a teenager from Northern Ireland caused a furore when she performed sex acts on 24 men on one of the pub crawls.
