What the actual fuck are you talking about. Speak English and try not to be so obvious about what you're asking.
All financial firms have responsibilities around AML and KYC. Since PSD2, which took effect last year, the scope of those responsibilities and the kinds of companies which have to report SARs (Suspicious Activity Reports) has greatly increased. Simply put, any deposit or movement of money over a certain amount is reported, and the limit for that has been greatly lowered; you would be surprised how many companies do these kinds of reports - everyone working online, for instance.
There isn't an easy way to launder money - and its getting much harder to do so. It's the laundering part of the crime where people usually get caught nowadays, it's far easier for the police to "follow the money" rather than catch you at a particular crime, and so that's what they focus on.
There is nothing happening in Brexit which will make it easier, or make money laundering more likely. Your assumptions are completely wrong and your request is way too transparent.
