Why UK Citizens Want a Second Passport
The demand for second passports for UK citizens has grown rapidly especially since Brexit.
While British passport holders still enjoy relatively strong global access, many are seeking backup citizenships for greater flexibility, opportunity, and peace of mind.
- Global mobility post-Brexit: The loss of EU freedom of movement has made travel, work, and residency across Europe more difficult. A second passport, particularly from an EU member state, can restore those privileges.
- Tax planning and investment diversification: Some countries offer favorable tax regimes or open access to specific investment opportunities, making a second citizenship part of broader gestione patrimoniale strategies.
- Enhanced safety and political stability: Geopolitical shifts, domestic policy changes, and future economic uncertainty have motivated many to secure a “plan B” in a politically stable country.
- Family legacy and future-proofing: A second passport can offer long-term advantages for children, including education access, global career prospects, and generational wealth preservation.
So, what is the best country to get a second passport?
The answer depends on your goals; whether they’re lifestyle-driven, tax-motivated, or focused on security and travel.
We’ll explore top options in the next sections.
