Are there any countries you cannot enter with a British passport?

Question

And more specifically, that you would be able to enter on an Irish passport? Though I doubt that so the answering just the 1st parts' fine!

Answer 1

There's very few countries in which a British National requires a visa to enter.  A good example is China which pretty much requires all visitors to get a visa prior to arrival.

Here's a list of countries where visas are not required when holding a British passport:

Answer 3

THE ANSWER ABOVE IS INCORRECT. THOSE ARE COUNTRIES THAT MAY ENTER THE US WITHOUT A VISA.

To answer the question, as far as I am aware, a British passport is good for all countries, although you may need a visa or other requirements for many. I think the passports used to be endorsed "Valid for all countries" but they removed it because it was taken as a given that you could travel anywhere with it.

An Irish passport is also a good passport: you are allowed into any country as far as I know (notwithstanding visas etc).
