My brother stupidly took out a loan for a few thousand pounds to consolidate 2 credit cards he had maxed out. Now he has the loan to pay and he has been using the credit cards again, so they have balances and payments each month. He cannot afford to repay all these payments. Any advice?
Unfortunately that is what happens sometimes when people consolidate credit cards or loans, they continue to use the consolidated accounts.
Some options your brother may have depends on what he can afford.
He may want to look into a token payment plan for the credit cards, if he thinks his situation will improve.
Your brother also may want to seek help with budgeting and spending.
