I am happy to send you my cantab LLM one, but please note that it's not actually a 'personal statement'. Instead, they ask for a 'reason for applying', which is akin to a PS but has elements missing that ought to be included in an actual PS (e.g: career/professional goals, which were asked as a separate question). I can also send you my PS for the BCL but it is awfully short (300 words), and would not suffice for any course that places a great deal of weight on the personal statement.
Let me know if you still want them and I'm happy to dig them out
