and if he gives birth to a child in the uk can he pass he ROB TO HIS CHILD ?
Is the British parent a British citizen under British law? (The fact that he might not want British nationality and has never, say, had a British passport doesn't alter his status under British law one way or the other.)
If the British parent is a British citizen otherwise than by descent (i.e. by virture of birth in the UK in this case, since presumably a past naturalisation is not in the equation here, based on what you say), then his or her child is almost certainly British by descent. If the British parent is a British citizen by descent, then things become more complicated.
If the British parent has the right of abode in the UK but is not a British citizen, then a child born outside the UK will not have the right of abode. A child born in the UK to such a person is, however, a British citizen by birth.
So, on what basis does the parent have the right of abode? The answer to that question will determine a lot of the answers.
