In 1920, at the first World Scout Conference, the individual national Scout Associations (such as the Spanish ASDE & MSC), agreed that "visiting nations" would not take host national children and affect their local recruitment.
The only exceptions to this are when the parents are prepared to take an active part in helping run the 'visiting' Group or the child was a part of British Scouting previously while in the UK as an 'expat' there and wishes to continue with the UK Scout program.
That agreement is still in place and has to be respected according to British Scouting Overseas agreements with the Spanish Scouting organisations.
