IoM has MPs, just not UK MPs. The OP almost certainly meant an MP from the Manx Tynwald parliament.

It doesn't though, that's my point. The Isle of Man has MHKs and ministers, not "MPs": https://en.wikipedia.org/wiki/House_of_Keys.

It's like saying a politician in the UK is a "senator" and expecting people think you are an authority on the subject.
