Dual Residence

Do I lose my English Tax Residence Status if I apply for Spanish Residencia?  Before everyone rushes to get Spanish Residencia, they need to consider the disadvantages as well as any perceived benefits.

I intend keeping my main home in England and not breaching the 183-day rule. I found this helpful article (link below)

but I'm not sure if I unfortunately die in Spain and am cremated there, whether I need to ensure my ashes are returned to England. so that my English AND Spanish properties (residences) are not deemed to be under the Spanish Inheritance system. Has anyone  any experience? I culd only find this:
