I won a good amount of cash at the weekend (£6000!!) at a casino. Can I just deposit it at my bank? Or are they going to ask me questions for tax reasons?? If it helps it's still in the casino sealed money bag things...
Would love to pay off my credit card and then treat myself 
FYI I'm not a regular gambler and don't plan to become one - this was a complete one off, on the roulette wheel no less
but I don't want them to start thinking I'm a money launderer or something!!
