Ian is an accountant and one of his clients is Jet, who runs an illegal operation as well as some other legitimate businesses. Jet approached Ian for advice as to how he should deal with the gains he makes from the illegal operation.Ian suggested that, rather than try to use his existing legitimate businesses to disguise the source of the money, Jet should use his legally made money to buy the local football club, Kickers, with the intention of passing his gains from the illegal operation through its accounts.Ian’s reasoning was that as there was a lot of cash going through the football club on a weekly basis, and as there appeared to be very little control exercised over the finances of football clubs, it would be easy to mingle the illegal money with the football club’s legitimate receipts.Jet accepted the proposal, bought the club, appointed Ian as its finance director and together they passed the illegal money through the football club. Lol, the long-term team manager of Kickers, has noticed the increase in the club’s income, but is concerned that the extra money is going to Jet as the owner, and not being used to finance the club.Required:Analyse the scenario from the perspective of the law relating to money laundering, advising Lol as to the legality of the above situation and what action can be taken against Ian and/or Jet.
