19 down: South American banker burst into Wheels of Fortune? (7)
DA has been found out! The answer here is limpopo, which Google tells me is the name of a province in South Africa and a river in southern Africa. DA was nasty enough to make banker = river, but it’s ever so splendid to see that such nastiness did him no good because he made reference to the wrong continent. The clue should have been Southern African banker burst into Wheels of Forune?, with the explanation burst = pop and wheels of fortune = limo, giving burst into Wheels of Fortune = limpopo = southern African banker.
