UK Visa Sponsorship

UK Visa
#1

If my sponsor (my uncle) is a businessman (sole owner of his business) with only a current bank account (which has sufficient funds) and no significant balance in his savings account.

  1. Would this affect my application?
  2. What documents will I have to provide showing that the funds in his current account are available for him to sponsor me?
