Daylesford, Australia, May 12 2016 (IPS) - A previously little-known law firm called Mossack Fonseca, based in Panama, has recently been exposed as one of the world’s major creators of ‘shell companies’, that is, corporate structures that can be used to hide the ownership of assets. This can be done legally but shell companies of this nature are widely used for illegal purposes such as tax evasion and money laundering of proceeds from criminal activity.
