Hi, native speaking English teacher here. Let me help with this « my partners have been British » drama. This is present perfect tense. A better sentence would have been « I HAVE HAD partners who have been British. » But in a rushed interview environment and editing, this was a quicker way for Gillian to express that part of the reason she has a British accent is that her « partners have been British. » This doesn’t imply at all than ALL partners (& children) have been British, just that some HAVE. Thanks Ma’am 🙂
