Aussie mining tycoon Robert de Crespigny....going to Scarborough fair?!?!?

Its the EPT disclosure by Collins Stewart, stating how many shares bought/sold and the execution price. I presume its compulsary for a broker acting for a company undergoing a merger (not sure it applies to aim though) who are also at the same time servicing their clients needs. I.e Collins Stewart has acted on behalf of their client, or have themselves, bought/sold some SCRB shares, therefore for transparency, because they are acting for SCRB in some form (consultant, broker etc) they must reveal their transaction. Otherwise i suppose it could be classed as insider trading as they may have inside info. There have been almost one-a-day over the past few weeks.
