Michael Portillo lives primarily in the UK but also has a second home in Spain. Specifically, he and his wife Carolyn have a home in the southern region of Spain, in the town of Carmona, about 20 minutes outside Seville. They make several trips a year to this Spanish home, which has historic significance with features like Roman mosaics and Islamic arches found underneath its floors. Michael Portillo is half-Spanish and has a strong connection to Spain, reflected in his choice to have this second residence there.
His main residence is generally understood to be in London, UK, where he has been described as relaxed and expansive in his garden.
Thus, Portillo divides his time between his home in England and his Spanish retreat in Carmona near Seville.
