The Financial Services Authority (FSA) has charged seven people in relation to alleged insider dealing in the latest crackdown on market abuse by the City watchdog.

The group faces charges on 13 counts of insider trading following a 21-month investigation which relates to dealing in shares of 12 companies, including Morgan Crucible, Misys, Reuters and Enodis, between 2006 and 2008. According to the FSA, activity during the two-year period involved alleged unlawful profits of around £2.5m.
