Moody, 47, learned he had the degenerative, muscle-wasting condition two weeks ago and has told BBC Breakfast that he is struggling to confront the implications of his diagnosis.

Because for Pembroke - who has only 10% vision having been diagnosed with a degenerative eye condition, retinitis pigmentosa, when he was six - it's not just about beer.
