The UK is sort of Protestant, it depends on how you phrase the question. About 60% of people consider themselves Christian, but anywhere between 50 and 70% of people would say that they’re are not religious.
For example, my little brother, who got married in our village church, but isn’t religious, and only goes into a church for social reasons.
Anecdotally, my French friends think that the British get married more than ‘usual’, and we have the same feeling about the US.
