Have a look at this excellent answer about demonstrating your general financial standing Should I submit bank statements when applying for a UK Visa? What do they say about me? If you did not need the loan from your friend to satisfy these points then possibly providing an explanation about the loan will suffice. If not, then your best option would be to wait until your financial history is βcleanβ before applying for a visa. Having your brother as a sponsor does not guarantee that your application will be approved - you will still need to demonstrate your financial standing.
