UK authorities could follow the example of their American counterparts in their probe into whether HSBC's Swiss private bank helped its customers dodge taxes.When US authorities prosecuted Swiss banks, including UBS and Credit Suisse, for helping US customers to evade taxes, they based their cases on the fact bankers did not limit themselves to service clients from Switzerland but travelled to the US to increase the business.A similar approach might have to be followed in the UK, where prosecution against HSBC or any member of the bank's staff could depend on whether the lender'sSwiss private banking unit sent staff to Britain and helped clients to evade British taxes and whether HSBC's executives were aware of any such practice."If there were conversations here, in furtherance of an agreement to commit dishonest tax crime, then that would be enough to give the UK jurisdiction," Monty Raphael, a lawyer who specialises in white collar crime and tax cases was quoted as saying by Reuters.
