UK Visa Sponsorship

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?

I am planning to apply for plab 2 visa .
My father has money but his bank account is not active so if he can’t sponsor a trip. Does anyone else apart from family can sponsor a trip if he have enough amount to sponsor a trip ?

It should not affect your application by any means.

You will need a cover letter stating he is providing the finances for you and bank statements. That should be more than enough.
