Best second passport for British citizens in 2026

A second passport for British citizens.

The 8 citizenship by investment programs on the Patrician.ch passport table, with the destinations each opens, the time, the published minimum, and what the United Kingdom says about keeping both.

In short, current to September 2026

The United Kingdom on dual nationality: Yes. A second passport sits beside it.
Your passport opens 186 destinations visa free or on arrival. None of the 8 programs opens more by count, so the reach a second passport adds is the destinations the first does not cover.
